Sen. Cory Booker’s Oura ring wants him to “pay attention” to his wellness.

The popular health-monitoring device that measures stress and tracks sleep didn't have great news for the New Jersey Democrat when he pulled an all-nighter and then some giving a marathon speech on the Senate floor this week.

The ring’s statistics show that Booker didn’t sleep during his 25 hours protesting Trump administration policies and is now suffering because of it. His stress levels are high, and his body has not been able to fully recover, according to screenshots of the app shared with NBC News.

As of this afternoon, no call had been scheduled between Trump and Russian President Vladimir Putin, according to two administration officials. Trump’s inner circle is advising him not to have a call with Putin until the Russian leader commits to a full ceasefire, the officials said.

The administration officials cautioned that Trump could decide he wants to talk to Putin suddenly. But they said he has been advised that a phone call is not a good idea unless Putin has conveyed to the White House that he agrees to a full ceasefire in the Russia-Ukraine war.

Trump told NBC News on Sunday that he planned to talk to Putin this week. He also said he was “very angry” at Putin for saying Ukrainian President Volodymyr Zelenskyy should step down from power.

The lack of direct communication between Trump and Putin comes as a Russian official met with White House officials and Republican lawmakers at the White House last night, according to three U.S. officials familiar with the meetings.

Trump won't be present today for the dignified transfer of four U.S. soldiers at Dover Air Force Base, Delaware. Instead, he'll be attending a LIV Golf dinner reception in Florida.

The White House and the Defense Department did not immediately respond to requests for comment on which administration officials might be in attendance.

The soldiers died during a training exercise in Lithuania. They were honored during a dignified departure ceremony from Lithuania, with Lithuanian President Gitanas Nausėda and other dignitaries paying tribute.

The 3rd Infantry Division identified the soldiers as Sgt. Jose Duenez Jr., 25, of Joliet, Illinois; Sgt. Edvin F. Franco, 25, of Glendale, California; Pfc. Dante D. Taitano, 21, of Dededo, Guam; and Staff Sgt. Troy S. Knutson-Collins, 28, of Battle Creek, Michigan.

The Republican-led Senate voted 52-48 on Thursday to begin debate on a budget blueprint for a multitrillion-dollar package to pass President Donald Trump’s agenda.

The measure calls for a steep tax cut and a spending increase for immigration enforcement and a Pentagon expansion, alongside unspecified spending cuts and a $5 trillion debt limit increase. It is likely to substantially increase the budget deficit.

Every Republican voted for the measure except Sen. Rand Paul of Kentucky. Democrats unanimously voted against it.

Democratic officials in 19 states filed a lawsuit Thursday against President Donald Trump's attempt to reshape elections across the U.S., calling it an unconstitutional invasion of states' clear authority to run their own elections.

The lawsuit is the fourth against the executive order issued just a week ago. It seeks to block key aspects of it, including new requirements that people provide documentary proof of citizenship when registering to vote and a demand that all mail ballots be received by Election Day.

“The President has no power to do any of this,” the state attorneys general wrote in court documents. “The Elections EO is unconstitutional, antidemocratic, and un-American.”

Trump's order said the U.S. has failed “to enforce basic and necessary election protection." Election officials have said recent elections have been among the most secure in U.S. history. There has been no indication of any widespread fraud, including when Trump lost to Democrat Joe Biden in 2020.

Trump told reporters on Air Force One that he wants tech billionaire Elon Musk, the head of the Department of Government Efficiency, "to stay as long as possible."

But he also said, “There’ll be a point where he’s going to have to leave," in part because of the companies he runs.

Asked by a reporter how long he anticipated Musk, classified as a special government employee, would work in his administration, he responded, "I mean, as long as he'd like."

Asked for a specific date on Musk's departure, Trump said, "I would think a few months."

A federal judge will temporarily block President Donald Trump’s administration from cutting billions in federal dollars that support COVID-19 initiatives and public health projects throughout the country.

U.S. District Judge Mary McElroy, appointed by Trump in 2019 but first nominated by former President Barack Obama, in Rhode Island said Thursday that she plans to grant the court order sought by 23 states and the District of Columbia.

“They make a case, a strong case, for the fact that they will succeed on the merits, so I’m going to grant the temporary restraining order,” said McElroy, who plans to issue a written ruling later.

The fallout from President Donald Trump's aggressive new tariffs has spurred Congress into action, with a growing number of Republicans joining Democrats to express interest in using their power to restrain him.

After the GOP-led Senate delivered a rare rebuke to Trump on Wednesday by voting to undo his tariffs on Canada, lawmakers in both chambers are weighing additional steps to rein him in. Senators are eyeing other mechanisms to rescind Trump’s existing tariffs while limiting his ability to impose new ones.

And Democrats in the House are exploring ways to force a vote to revoke Canadian tariffs, putting out feelers to attract support from Republicans.

Now that President Donald Trump has set out his landmark tariff plans, the Federal Reserve finds itself in a potential policy box to choose between fighting inflation, boosting growth — or simply avoiding the fray and letting events take their course without intervention.

Should the president hold fast to his tougher-than-expected trade policy, there's a material risk of at least near-term costs, namely the potential for higher prices and a slowdown in growth that could turn into a recession.

For the Fed, that presents a potential no-win situation.

A federal judge said Thursday that the Trump administration may have "acted in bad faith” by trying to rush Venezuelan migrants out of the country before a court could block their deportations to El Salvador.

U.S. District Judge Jeb Boasberg in Washington pressed a Justice Department lawyer to explain the government's actions in a high-stakes court hearing to determine whether the administration ignored his orders to turn around planes that were carrying deportees to El Salvador.

The judge said he could issue a ruling as soon as next week on whether there are grounds to find anyone in contempt of court for defying the court order.

The Senate voted to confirm celebrity doctor Mehmet Oz as the head of the Centers for Medicare and Medicaid Services by a party-line vote of 53-45.

Oz came under fire for questions if he may have underpaid Medicare and Social Security taxes, per a Senate Dem memo. 

Major stock indexes saw their worst one-day drawdowns since the onset of the Covid-19 pandemic Thursday.

The S&P 500 fell 4.8%, while the Nasdaq fell 6% — both their worst since 2020. The Dow Jones Industrial Average declined 4%, or more than 1,600 — its worst sell-off since 2022.

The value of the United States dollar saw one of its biggest drops in years today, down as much as 2.2%.

In theory, that's good news for the export-oriented agenda Trump is espousing, and which he hopes his tariffs will help put into effect. If the value of U.S. goods go down, it makes them easier to sell abroad.

But by and large, the United States doesn't have a problem selling goods abroad. Instead, its trade deficit is the product of our ability to buy even more stuff than we sell.

With a weaker dollar, the average consumer in the United States will have less overall buying power.

Notably, White House officials, including Treasury Secretary Scott Bessent, in his confirmation hearing, and Stephen Miran in a 2024 paper, said that assuming tariffs did cause prices to go higher, the impact to U.S. consumers from tariffs would be less severe as long as the dollar appreciated in value.

The Pentagon’s acting inspector general announced Thursday that he would review Defense Secretary Pete Hegseth’s use of the Signal messaging app to convey plans for a military strike against Houthi militants in Yemen.

The review will also look at other defense officials' use of the publicly available encrypted app, which is not able to handle classified material and is not part of the Defense Department’s secure communications network.

Hegseth’s use of the app came to light when a journalist, Jeffrey Goldberg of The Atlantic, was added to a Signal text chain by national security adviser Mike Waltz. The chain included Hegseth, Vice President J.D. Vance, Secretary of State Marco Rubio, Director of National Intelligence Tulsi Gabbard and others, brought together to discuss military operations against the Iran-backed Houthis.

President Donald Trump fired at least three National Security Council officials this week after far-right activist Laura Loomer met with the president and expressed dissatisfaction with some officials on his national security team, three people familiar with the matter told NBC News.

Among those let go were senior officials Brian Walsh, Thomas Boodry and David Feith, the sources said.

Secretary of State Marco Rubio arrived in Brussels today for his first NATO meeting as secretary an hour behind schedule after attending the lengthy Trump tariff event yesterday — flying overnight to find Europe rattled by the higher-than-expected tariffs and already anxious over being cut out of the U.S.-Russia talks on Ukraine and suggestions the United States might draw down forces in Europe.

Alongside Secretary-General Mark Rutte, Rubio restated U.S. commitment to NATO, blaming “hysteria and hyperbole” on global media (not repeated Trump criticism of NATO).

Rubio avoided tariff questions, but before he arrived, Norway and others complained about them. Rubio met with Danish Foreign Minister Lars Rasmussen and ducked a shouted question about Greenland. He was not slated to meet separately with Ukraine's foreign minister who was attending.

In a gaggle with NBC News and Danish press, Danish Foreign Minister Lars Rasmussen said President Donald Trump was wrong to start a trade war and it is bad for the global economy. He said he will be attending a meeting of European trade ministers Monday and they will avoid escalating but will come up with a “proportional” response.

He also said the president’s calculations don’t take into account the services sector in which Denmark’s savings are heavily invested in the U.S.

Separately he excoriated Trump for telling NBC News' Kristen Welker on "Meet the Press" that he wouldn’t rule out military force against Denmark, a NATO ally, if necessary to get Greenland.

Digital currencies were not immune to Thursday's sell-off. Bitcoin prices fell as much as 6% on the day to about $81,000, its lowest level in nearly a month, according to CoinMarketCap.com, which tracks token prices. Ethereum, the next-most-valuable digital token, was off as much as 7% to about $1,700.

Trump's own meme coin was not immune, falling more than 14% to less than $9.

Trump’s tariffs announced yesterday will cost the average household around $2,100 a year with the lowest income households facing an extra $980 in annual costs, according to an analysis by The Budget Lab at Yale University.

When factoring in all the tariffs Trump has announced since taking office, including those on Mexico, Canada and all steel and aluminum imports, that cost rises to $3,800 for the average household and $1,700 for the lowest income households.

The analysis estimates that Trump’s various tariffs announced over the past two months will increase the price of all leather goods, including shoes, by 18%, clothing by 16%, electrical equipment by 10% and fish and fresh produce by 4%.

Combined, Trump’s tariffs will increase prices around 2.3%, the report found. That amount would come on top of the roughly 3% inflation rate the U.S. has already been experiencing.

In explaining how they came up with Trump’s tariff rates, the U.S. Trade Representative put out a seemingly complicated formula that likely sent a chill down the spine of anyone who didn’t treasure their time in math class. 

The White House has denied its tariff number is based off simply dividing the trade deficit by a country’s imports. But if you read a little further down the page, everything becomes much simpler. 

ε (sigma) and φ (phi) seem like complicated variables that would make solving this equation difficult for anyone except a mathematician. But according to the trade rep’s own explanation, the numbers those variables represent cancel each other out. 

“The price elasticity of import demand, ε, was set at 4. …  The elasticity of import prices with respect to tariffs, φ, is 0.25.”

Technology stocks plummeted today after President Donald Trump’s new tariff policies sparked widespread market panic.

Apple led the declines among the “Magnificent Seven,” dropping nearly 9%. The iPhone maker makes its devices in China and other Asian countries. The stock is on pace for its steepest drop since 2020.

Other megacaps also felt the pressure. Meta Platforms and Amazon fell more than 7% each, while Nvidia and Tesla slumped more than 5%. Nvidia builds its new chips in Taiwan and relies on Mexico for assembling its artificial intelligence systems. Microsoft and Alphabet both fell about 2%.

Semiconductor stocks also felt the pain, with Marvell Technology, Arm Holdings and Micron Technology falling more than 8% each. Broadcom and Lam Research dropped 6%, while Advanced Micro Devices declined more than 4%. Software stocks ServiceNow and Fortinet fell more than 5% each.

Trump administration officials fanned out across morning news shows to defend the White House's new tariffs as global markets reeled from yesterday's announcement.

White House press secretary Karoline Leavitt urged Wall Street to "trust in President Trump" and rejected the idea that Trump would pull back on tariffs before they go into effect.

"The president made it clear yesterday this is not a negotiation — this is a national emergency," she said in a CNN interview.

Vice President JD Vance said on Fox News that workers who joined Trump yesterday during the announcement "know this is a big change," adding, "but we need a big change in this country."

In a CNBC interview, Commerce Secretary Howard Lutnick said that he wanted countries to "stop picking on us." He also asked why products like iPhones could not be made in the U.S.

A chart from Evercore ISI, an investment banking firm, highlights just how big Trump's tariffs are.

The firm below charts average U.S. tariffs, with the sizable and historic Smoot-Hawley Act toward the left. To the right, you can see just how aggressive Trump's tariff plan is: Evercore estimates that U.S. tariffs will exceed a weighted average of 25% — well above Smoot-Hawley.

Federal job cuts resulted in the U.S. seeing the third-highest number of layoffs ever recorded in a single month in March, according to a report from jobs and career consultancy Challenger, Gray & Christmas, Inc.

The report said cuts enacted by the Department of Government Efficiency, the effort spearheaded by Elon Musk that's helped scramble the federal workforce, had resulted in 216,215 layoff plans of federal workers and contractors impacting 27 agencies.

In total, 275,240 cuts were registered across the U.S. economy.

“Job cut announcements were dominated last month by Department of Government Efficiency [DOGE] plans to eliminate positions in the federal government. It would have otherwise been a fairly quiet month for layoffs,” Andrew Challenger, senior vice president and workplace expert for Challenger.

So far this year, employers have announced 497,052, the highest year-to-date and quarterly total since Q1 2009, Challenger said.

Fresh off the dissolution of his criminal corruption case, New York City Mayor Eric Adams says he's back to focusing on working for New Yorkers. He just plans to do it with another party.

The embattled Democrat announced Thursday that he will run instead for mayor as an independent, leaving Andrew Cuomo, who resigned as governor of New York amid a sexual harassment controversy, the primary contender at the top of the blue ticket. City Council Speaker Adrienne Adams is also running.

Leaders from around the world reacted to President Trump’s sweeping tariffs, many saying they regret the decision from the White House.

European Commission President Ursula von der Leyen said the tariffs are a “major blow to the world economy.”

Many of the world’s poorest countries now face the highest reciprocal tariffs imposed by Trump yesterday.

Lesotho in southern Africa has been slapped with the highest duty of 50%. Listed as the world’s 22nd poorest country, it primarily exports diamonds and garments, with the U.S. as one of the top five exporting destinations.

Cambodia is hit by 49% U.S. tariffs, the second highest, though the U.S. is Cambodia’s largest single-country export destination.

Madagascar in east Africa, the world’s ninth poorest country, will face 47% reciprocal tariffs. It primarily exports vanilla, cloves and garments, with the U.S. among the top five countries it exports to.

Calling the U.S. tariffs "extremely regrettable," Japan said it will examine the impact on domestic industries and will take "all necessary measures," including providing support for cash flow.

"We will promptly establish a special consultation service and provide support for cash management and fund procurement," chief cabinet secretary Yoshimasa Hayashi told reporters in a regular news briefing.

Hayashi said he would not disclose the "specifics of what is being considered" when asked if Japan was considering arbitration by the World Trade Organization or reciprocal tariffs.

Japan's Nikkei index closed 2.8% lower Thursday.

The sweeping tariffs Trump announced yesterday stretched around the globe, including the remote Heard and McDonald Islands, which are populated by zero humans but lots of seals and penguins.

Despite having no apparent exports or imports, the sub-Antarctic islands, which are an external territory of Australia, will be subject to a 10% tariff, according to a document the White House provided during Trump’s tariff announcement yesterday.

Other tiny nations and territories were also hit with 10% tariffs, including Tokelau, a dependent territory of New Zealand, with a population of around 1,600 people, and the Cocos Islands, another territory of Australia, with a population of around 600 people.

French officials slammed President Trump’s 20% tariff measures on all goods imported from the European Union, saying that the bloc could be expected to retaliate in mid-April, and then again in late April.

The first of the two responses by the EU will tackle Trump’s attacks on aluminum and steel, followed by the broader range of products and services, French government spokesperson Sophie Primas told local broadcaster RTL radio Thursday.

“We are also going to attack services,” she said, including online services from Google, Apple, Facebook, Amazon and Microsoft. She added that the EU would also review access of U.S. companies to procurement contracts in Europe.

France is “ready in this trade war,” Primas said, after accusing Trump of behaving like he’s “master of the world” and of having an “imperialist posture.”

President Donald Trump has favored tariffs for years. His expanding trade war is sure to ripple through the global economy for a long while, too.

That’s because ramping up tariffs on foreign governments frequently draws retaliation — a likelihood that even industries Trump aims to support are already bracing for. While he has been rolling out an ever-shifting series of import taxes for months, the sweeping “reciprocal” tariffs he announced yesterday are opening salvos in what could become drawn-out tit-for-tats with potentially dozens of governments.

Unlike the narrower, targeted tariffs Trump imposed on certain countries and products in his first term, his latest duties are set to rewrite the rules of global trade on a far broader level — and in an environment in which inflation is running hotter.

“This is a game changer, not only for the U.S. economy but for the global economy,” Olu Sonola, head of U.S. economic research at Fitch Ratings, said in a note Wednesday evening.

“Many countries will likely end up in a recession. You can throw most forecasts out the door, if this tariff rate stays on for an extended period of time,” she said, adding that the levels Trump is introducing haven’t been seen since 1910.

A handful of Republican senators told NBC News tonight that Trump's decision to place tariffs on more than 180 countries and territories could lead to short-term pain for U.S. consumers in the form of higher prices.

“Sometimes in business you have to have short-term pain to have long-term gain, and we don’t think this is even going to be that long of a short term, if it is at all. We trust the president,” Sen. Markwayne Mullin, R-Okla., said.

Sen. Cynthia Lummis, R-Wyo., said Trump acted "pretty responsibly" in implementing the tariffs but still acknowledged "there could be short-term pain" in response to the import penalties.

"I’m looking forward to seeing how they work. We already have countries that have approached the president to say: 'We want to work with you. We’ll lower our tariffs, if you lower yours,'" Lummis said.

Sen. John Kennedy, R-La, said he's confident Trump will reconsider the tariffs if there's a significant impact on U.S. consumers.
