Trump admin live updates: Senate to begin 'One Big Beautiful Bill' vote-a-rama Monday

Senate Republicans announced Sunday that they planned a brief pause on the precession of events toward a final vote on the "One Big Beautiful Bill."

Senators will begin their vote-a-rama at 9 a.m. Monday, instead of the original early early morning start time that was anticipated. In the meantime, debate of the bill will continue on the Senate floor until senators finish or their time expires.

Once the vote-a-rama kicks off, senators will be allowed to offer an unlimited number amendments to the bill. When this ends, they'll take a vote of final passage. It will need 51 votes to pass.

A fiery Sen. Thom Tillis, R-N.C., took to the Senate floor on Sunday evening to explain his vote from Saturday against the motion to proceed on the One Big Beautiful Bill Act, condemning the legislation and saying it breaks President Donald Trump’s promises to protect Medicaid.

“What do I tell 663,000 people in two years, three years, when President Trump breaks his promise by pushing them off of Medicaid because the funding is not there anymore, guys?” Tillis asked at one point.

“The people in the White House advising the president, they're not telling him that the effect of this bill is to break a promise.”

Tillis, who had earlier on Sunday announced his plans to retire from the Senate following attacks from Trump over his decision to oppose the GOP megabill, also said that the president’s self-imposed July 4th deadline to pass the legislation was “artificial.”

“I believe that we can make sure that we do not break the promise of Donald J Trump– that he's made to the people on Medicaid today,” Tillis continued. “But what we're doing because we've got a view on an artificial deadline on July 4 that means nothing but another date and time we could take the time to get this right, if we lay down the house mark of the Medicaid bill and fix it."

"What’s wrong with actually understanding what this bill does?" the senator asked.

As the Senate officially began debating the "big beautiful bill," President Donald Trump took to his social media platform on Sunday, advising Republican senators not to "go too crazy!" and suggesting that they still need to be reelected.

"For all cost cutting Republicans, of which I am one, REMEMBER, you still have to get reelected," Trump wrote on Truth Social. "Don’t go too crazy! We will make it all up, times 10, with GROWTH, more than ever before," he added.

The president's comments come as a number of Republican senators who voted to advance the bill on Saturday said they are still considering how they'll vote on its final passage.
