Trump admin updates: Trump calls for expanded deportations in LA, NYC and more

Sen. Tammy Baldwin, a Wisconsin Democrat, pressed Defense Secretary Pete Hegseth on the specific legal statute President Donald Trump is relying on to send active duty Marines to Los Angeles.

"The president has constitutional authority," Hegseth began. Baldwin interrupted to ask him to "cite the provision of the Constitution."

"I'd have to pull up these specific provisions, but our Office of General Counsel, alongside our leadership, has reviewed and ensured, in the order that we set out, that it's completely constitutional for the president to use federal troops to defend federal law enforcement," Hegseth said.

"I'd like to know the specific constitutional statutory authority," Baldwin responded. "The president made it clear that he relied on Section 12406 of Title 10 with regard to the National Guard troops. I need to know the authority that he is relying upon in terms of active duty Marines being deployed to California."

Sen. Brian Schatz, D-Hawaii, questioned Dan Caine, chairman of the Joint Chiefs of Staff, about Trump's immigration policies and the administration's claims that the country is being invaded.

Cain testified that "at this point in time, I don't see any foreign, state-sponsored folks invading, but I'll, you know, be mindful of the fact that there has been some border issues throughout time."

Schatz then asked if there was an active rebellion in the United States.

"I think there's definitely some frustrated folks out there," Caine responded.

Democratic Sen. Jack Reed pressed Defense Secretary Hegseth for specifics on the luxury jet from Qatar being offered to the U.S. to be used as Air Force One.

"Are you in possession of the Qatari airplane now?" Reed asked Hegseth.

"Any specifics about future aircraft that could be Air Force One can't be discussed here," Hegseth said.

Hegseth went on to state the "memorandum of understanding remains to be signed" in terms of the deal. A White House official told ABC News in late May that the White House's legal team was finalizing the details of the gift and working on an MOU between the U.S. and Qatar. The plane from Qatar is currently in the United States, according to sources familiar with the matter as well as President Trump.

Reed also pressed the defense secretary for specifics on contracts and costs to modify the jet, as well as when it would be delivered.

"

"The delivery time of anything of that sensitive nature is not for public consumption," Hegseth replied.

Sen. Jack Reed, D-R.I., brought up the situation in Los Angeles and questioned Defense Secretary Pete Hegseth about the administration's use of National Guardsmen and Marines to deal with the protests.

The senator said this week the Dept. Homeland Security sent a request to the Defense Department "to authorize military forces to detain or arrest American citizens, to provide D.H.S. with military drone surveillance support and to have the Marine Corps advise D.H.S. on running joint operations."

"Every authorization we provided the National Guard and the Marines in Los Angeles is under the authority of the president of the United States is lawful and constitutional," Hegseth said.

Hegseth argued that the military use in the city was part of an effort to maintain "law and order," but the senator pushed back.

"Law and order is a civil function under the Constitution of the United States. Civil enforcement, law enforcement authorities, not the U.S. military," Reed said.

"This is not only, I think, illegal, but also a diminution of the readiness and focus of the military," he added.
