Trump 2nd term live updates: Senators blast Trump over IG firings

A federal judge slammed Trump's executive order seeking to end birthright citizenship as a "blatantly unconstitutional order."

"I have been on the bench for over four decades. I can't remember another case where the case presented is as clear as it is here," U.S. District Judge John Coughenour said minutes into a hearing on a legal challenge to the action.

Coughenour later signed a temporary restraining order blocking Trump's order.

Former Rep. Tulsi Gabbard's hearing for director of national intelligence will be held on Thursday, Jan. 30, sources told ABC News.

Gabbard's nomination has been scrutinized over her lack of intelligence experience and her echoing of Russian disinformation.

If confirmed, Gabbard would oversee a sprawling network of 18 agencies and a $100 billion budget. She's been making the rounds on Capitol Hill to shore up support among lawmakers.

Secretary of State Marco Rubio will take his first international trip in office next week, visiting Panama, Guatemala, El Salvador, Costa Rica and the Dominican Republic, according to the State Department.

Immigration is expected to be a key focus of the Trump administration. Rubio will encourage leaders to accept more of their deported nationals.

But the stop in Panama is especially notable given President Donald Trump's repeated threats to retake the Panama Canal.

Sen. Lisa Murkowski, considered a key GOP swing vote, said she will not be supporting President Donald Trump's Pentagon pick Pete Hegseth.

"After thorough evaluation, I must conclude that I cannot in good conscience support his nomination for Secretary of Defense," she said in a lengthy statement.

"I did not make this decision lightly; I take my constitutional responsibility to provide advice and consent with the utmost seriousness," she added.

The Senate is expected to take a procedural vote on Hegseth's nomination Thursday afternoon.
