Trump admin live updates: Trump strikes deals with law firms totaling $600M

Kathleen Sgamma, President Donald Trump's pick to lead the Bureau of Land Management, has withdrawn her nomination, the White House confirmed to ABC News on Thursday.

The withdrawal comes after it was reported that she wrote a memo in 2021 affirming the results of the 2020 election and criticizing Trump's role in the Jan. 6 Capitol riot.

"We accept her withdrawal and look forward to putting forth another nominee," White House spokeswoman Liz Huston said.

The announcement comes after the outlet Documented reported a memo that Sgamma allegedly sent while she was the president of Western Energy Alliance, an oil industry group.

The memo from Sgamma said she was "disgusted by the violence" at the Capitol on Jan. 6 and by his role in "spreading misinformation."

In the reported memo, Sgamma also said the election of President Joe Biden provided "hope for a resurgence of sanity" and she wished Biden well.

Sgamma didn't return messages to ABC News for comment.

State Department spokeswoman Tammy Bruce confirmed reports that U.S. Ambassador to Ukraine Bridget Brink would depart her post, but she didn’t give an exact timeline for when that was expected to happen.

"Ambassador Brinks has been ambassador at the embassy in Ukraine for three years during a time of war -- for those three years, an extraordinary performance there, and we wish her well," Bruce said.

Brink is a career diplomat and was nominated to the post in 2022 by then-President Joe Biden and confirmed that same year.

During Thursday's Cabinet briefing, Secretary of State Marco Rubio addressed the Trump administration's crack down on student visa holders who it alleges are breaking the law.

Rubio claimed that the United States is open to student visas but warned of people who allegedly "vandalize a library, take over a campus and do all kinds of crazy things."

"So when we identify lunatics like these, we take away their student visa. No one's entitled to a student visa," he said.

"The press of student visa is like there's some sort of birthright. No, a student visa is like me inviting you into my home. If you come into my home and put all kinds of crap on my couch, I'm going to kick you out of my house," he added.

President Donald Trump claimed during the meeting that the administration will provide some relief to farmers and hotel operators who employ immigrants lacking legal status.

"We have to take care of our farmers, their hotels and, you know, various, various places where they're usually where they need the people," he said.

"A farmer will come in with a letter concerning certain people saying they're great, they're working hard. We're going to slow down a little bit for them, and then we're going to ultimately bring them back. They'll go out, they're going to come back as legal workers," he explained.
