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

In an unsigned letter to the Trump administration this week, Tesla raised some concerns about the ongoing tariffs-- warning that they could be "exposed" to retaliatory tariffs and urging them to "consider the downstream impacts."

"As a U.S. manufacturer and exporter, Tesla encourages USTR to consider the downstream impacts of certain proposed actions taken to address unfair trade practices," the letter to to United States Trade Representative Jamison Greer said.

Tesla did not immediately respond to questions from ABC News, including who wrote the letter, which was dated March 11.

In the letter, Tesla noted that actions by the Trump admin have resulted in "immediate reactions" by the targeted countries, which include increased tariffs on electric vehicles.

"Trade actions should not (and need not) conflict with objectives to further increase and support domestic manufacturing," the letter said.

In a new Truth Social post Friday morning, President Donald Trump suggested that former President Joe Biden and other former administration officials should go to jail. In the post, Trump criticized Biden's handling of issues like the Israel-Hamas war, the economy and the border.

"Oh, what a difference A RIGGED & CROOKED ELECTION HAD ON OUR COUNTRY, AND THE PEOPLE WHO DID THIS TO US SHOULD GO TO JAIL!," Trump said in the post.

This comes as Trump is expected to give remarks at the DOJ later Friday.

The Internal Revenue Service expects to lose approximately 20% of its workforce -- or roughly 18,000 employees -- by May 15 as part of staff cuts directed by the Elon Musk-led Department of Government Efficiency, two sources familiar with the plans told ABC News.

That figure includes the probationary workers already dismissed and those who accepted the administration's "buyout" offer.

This unfolds as a federal judge ordered President Donald Trump's administration to rehire the fired workers at the IRS and five other agencies on Thursday — though the administration has filed a notice to appeal the ruling.

Amid tax season, the agency's taxpayer services and compliance departments will likely lose thousands of workers in what could be the first of several waves of firings, one of the sources said.

The Treasury Department and IRS did not return requests for comment on the potential cuts.
