Trump admin updates: Trump says tariff letters to be sent to 'various countries' on Monday

President Trump told ABC News Senior Political Correspondent Rachel Scott he's open to moving back the July 4 deadline he set for Republicans to send that massive tax and spending bill to his desk.

"I'd love to do July 4," Trump said as he took reporter questions while leaving the White House early Tuesday. "But I think it's very hard to do July 4. It was two months ago -- I would think maybe July 4, but somewhere around there."

It's a sign the president is aware of the political headwinds this bill is facing in the Senate.

ABC's Scott also asked the president about the holdouts. He delivered a veiled threat, saying Republicans who do not support the bill will "pay the consequences."

"I think it would be very wise for them to get on board. I really do," Trump said.

As Elon Musk again turns up his criticism on President Trump's megabill, Trump was asked by a reporter on Tuesday morning, "Are you going to deport Elon Musk?"

"I don't know. We'll have to take a look," Trump responded. "We might have to put DOGE on Elon. You know what DOGE is? The monster that might have to go back and eat Elon. Wouldn’t that be terrible? He gets a lot of subsidies.”

Musk, a South African native and a naturalized U.S. citizen, on Monday said he would back challengers to members of Congress who vote for Trump's so-called "One Big Beautiful Bill Act."

President Trump took several questions on the status of his "One Big Beautiful Bill Act" early Tuesday after an all-nighter in the Senate still didn't produce consensus among the Republican conference.

Departing the White House to visit a new "Alligator Alcatraz" migrant detention center in Florida, Trump said he would be back in Washington early on Tuesday afternoon to keep "fighting for the bill."

"I think we're doing well, we're going to have to see. It's very complicated stuff. Great enthusiasm as you know, and I think in the end we're going to have it," Trump said.

Trump also responded to Elon Musk's comments on the bill, as the world's richest man is threatening to primary Republicans who support it. Trump said Tesla CEO Musk is upset about the legislation removing tax credits for electric vehicles but warned that he "could lose a lot more than that."

"DOGE is the monster that might have to go back and eat Elon," Trump told reporters.

Trump was asked when he thinks he'll get final passage of the bill and he said "hopefully soon."

"I think Senate could be today, and then we'll go over to the House," Trump said.

Vice President JD Vance arrived on Capitol Hill early on Tuesday, in what may be a sign that the marathon "vote-a-rama" is heading toward a conclusion.

Vance will likely be needed to cast a tie-breaking vote on passing the bill.

When he entered, the vice president was asked whether he thought the bill would get over the finish line on Tuesday. "We're going to find out," Vance replied.

It's unclear whether Vance will further negotiate with holdouts or prepare to cast a final vote.

Majority Leader John Thune teed up three more votes on the Senate floor, but they are not expected to be the last of the amendment votes.
