Trump admin updates: White House asks court to stay order to ground deportation flights

In a letter to Congress, Postmaster General Louis DeJoy said the Postal Service plans to trim its workforce by 10,000 with voluntary buyouts in the next 30 days.

The agency has roughly 600,000 workers and has been exempt from the Trump administration's efforts to downsize the federal government and its workforce.

DeJoy also said the USPS has signed an agreement with the Department of Government Efficiency "to assist us in identifying and achieving further efficiencies."

Rep. Gerry Connolly, D-Virginia, the top Democrat on the House Oversight Committee, criticized the agreement and raised concerns the that it could lead to future privatization of the USPS, which Elon Musk has floated.

"The only thing worse for the Postal Service than DeJoy's 'Delivering for American' plan is turning the service over to Elon Musk and DOGE so they can undermine it, privatize it, and then profit off Americans' loss. This capitulation will have catastrophic consequences for all Americans," Connolly said. "Reliable mail delivery can't just be reserved for MAGA supporters and Tesla owners."

The Trump administration has asked the Supreme Court to significantly narrow nationwide injunctions issued by three different federal judges blocking his order redefining birthright citizenship in the U.S.

The emergency applications ask the justices to take a "modest" step and rollback the judges' restriction on President Donald Trump's Day 1 order, allowing federal agencies to move forward with developing guidance and preparing for implementation if, at the end of litigation, the president prevails.

As the clock ticks toward a government shutdown at the end of day Friday, President Donald Trump was asked if he'd get directly involved in negotiations with Senate Democratic Leader Chuck Schumer.

"If they need me, I'm there 100%," he responded.

He went on to preemptively blame Democrats if a shutdown were to occur and lauded the stopgap measure passed by House Republicans earlier this week. He said the bill was a funding "extension," but "ultimately we want to vote for one big, beautiful bill where we put the taxes in, we put everything in."

"Any chances you'll bend on the tariffs on aluminum and the ones that are planned for April 2?" a reporter asked President Donald Trump in the Oval Office on Thursday.

"No," Trump responded, repeating his administration's main argument that the United States has been taken advantage of in trade deals with other nations.

"No I'm not going to bend at all. Aluminum or steel or cars. We're not going to bend," he said.

The president railed against Canada, saying it "only works as a state" and that the United States doesn't need their lumber, energy or cars.

"There's not a thing that we need. Now there'll be a little disruption, but it won't be very long," Trump said. "We have to do this, I'm sorry."
