Republican Sen. Ron Johnson of Wisconsin -- a staunch deficit hawk has been critical of President Donald Trump's sweeping tax and immigration bill -- signaled Monday that he would back the bill when it comes to a vote. On Saturday Johnson flipped his vote to support a motion to move the One Big Beautiful Bill Act to the Senate floor only after huddling with Republican leaders about further reductions to the federal debt. CNN's Jake Tapper prompted Johnson to say he was a yes vote on the bill, to which the senator corrected him, saying he was "a yes on the motion to proceed" and "hopefully" add a provision that would prevent new enrollees in Medicaid expansion states from receiving Federal Medical Assistance Percentage (FMAP) if they are are not disabled and don't have dependent children.

"This is about as good as we can get. I don't like it. I would like to get a lot more. But at some point in time you have to recognize reality. And if we don't pass this bill, we have a massive $4 trillion tax increase," Johnson said. The FMAP amendment, led by fellow conservative holdout Sen. Rick Scott of Florida, had not yet been considered Monday evening. The Senate plowed ahead toward a final vote on the bill as Republicans rush to get it across the finish line by July 4, with lawmakers voting on amendments through the night into Tuesday morning. The self-imposed deadline by Trump meant a rare weekend session for lawmakers, one filled with partisan drama and some GOP infighting. On Monday morning, senators began the "vote-a-rama" -- a series of votes on proposed amendments to the megabill. There is no limit to the number of amendments lawmakers can seek. Senate Minority Leader Chuck Schumer, the chamber's top Democrat, promised his party would bring amendment after amendment during the marathon session. Democrats forced a reading of the 940-page bill over the weekend, which took nearly 16 hours. "Every senator will soon have an opportunity to reject this nonsense and vote for common-sense budgeting. Americans will be watching," Schumer said on Monday as he slammed Trump's bill as a break for billionaires that will hurt working-class families. Democrats used the early hours of the vote-a-rama to force votes highlighting cuts the megabill makes to Medicaid, SNAP and rural hospitals and to hammer Republicans on the tax cuts they say the measure gives to the wealthiest Americans. The Senate voted down, 47-53, an amendment led by Schumer that he said would have undone "the travesty that is at the core of the Republican bill." "Their bill the so-called big beautiful bill, which is really a big, ugly betrayal, cuts taxes for billionaires by taking away health care for millions of people. So what my amendment simply says, if people's health care costs go up, the billionaire tax cuts vanish," Schumer said. Democratic Sen. Ed Markey's effort to strip provisions that would negatively impact rural hospitals due to cuts to Medicaid also failed, but did receive the support of two Republicans: Sens. Lisa Murkowski of Alaska and Susan Collins of Maine. The two moderate Republicans, who both have a history of voting across party lines, have raised concerns about how cuts to Medicaid and SNAP would hit their constituents. In total, Murkowski supported five Democratic-led measures in the ongoing vote-a-rama and Collins supported four. Collins proposed her own amendment that aimed to increase the amount of money in the rural hospital relief fund. It failed by a vote of 22-78, with Collins subsequently criticizing what she called the "hypocritical approach" of the Democrats that voted against it. Sen. Amy Klobuchar, the top Democrat on the Senate Agriculture committee, argued that the SNAP provisions in the bill creates "chaos for state budgets and hardship for families" and violate budget rules. Her motion related to SNAP was waived by Republicans. Senate Majority Leader John Thune defended the bill as delivering Trump's campaign promises to eliminate tax on tips and overtime pay while boosting spending for defense and border security. "It's been a long debate," Thune said in his own floor remarks ahead of the votes on amendments. "I know people are weary. But at the end of the day, we want to get this done so that this country is safer and stronger and more prosperous, not only for today but for future generations of Americans." So far, Republicans have defeated all Democratic efforts to modify or reconsider the bill -- but the session ran into Tuesday morning. As he walked off the floor in the early hours of Tuesday, Thune was asked if he could pull the bill back or if he may be forced to hold a final passage vote on the bill, even if he knows it will fail. "Those are options I don't want to have to worry about," Thune replied. Senate Finance Committee chairman Mike Crapo, a Republican, argued against several of the Democratic amendments. "The reality is, the reforms we are putting into place are to try to reign in control of wasteful and fraudulent and abusive spending that actually diverts resources away from the people who these programs really deserve to receive," Crapo said of Schumer's amendment on Medicaid. The vote-a-rama is the last hurdle before a vote on final passage of the bill in the Senate. There is little room for error in the Republican-controlled chamber. A procedural vote on Saturday night to open debate on the bill narrowly passed in a 51-49 vote after two Republican defections. GOP Sens. Rand Paul of Kentucky and Thom Tillis of North Carolina voted against advancing the bill. Tillis railed against the changes to Medicaid in the bill, saying it would hurt his constituents and would represent a betrayal of Trump'spromise not to touch the entitlement programupon which millions of people rely for health care coverage. MORE: GOP Sen. Tillis won't run for reelection after Trump primary threat Tillis' opposition drew Trump's ire, with the president threatening to support a primary challenger to the two-term senator. Tillis then suddenly announced he would not seek reelection, saying later he texted Trump on Saturday night suggesting he "probably needed to start looking for a replacement." "I respect President Trump. I support the majority of his agenda, but I don't bow to anybody. When the people of North Carolina are at risk. And this bill puts them at risk," Tillis said. As of early Tuesday morning, the GOP leadership were still pushing for sufficient support. One of the main targets was Murkowski, whose indecision came after reports that the Senate parliamentarian may have ruled some carve out provisions meant for her home state of Alaska's Medicaid recipients out of order. Also under pressure were Scott and Sen. Mike Lee, who were yet to receive a vote on their amendment that strips back additional funding for Medicaid. Collins had also not yet said which way she would vote. Paul, meanwhile, offered an amendment that would significantly reduce the amount of money attributed to raise to the federal debt limit. The current bill raises the debt limit by $5 trillion dollars. Paul's amendment would raise it by only $500 billion. If the "One Big Beautiful Bill Act" passes in the Senate, it will have to go back to the House for members to consider the changes made to the bill. House Republican leaders say Wednesday is the earliest chance for a megabill vote. "Members are advised that votes are now expected in the House as early as 9 a.m. Wednesday, July 2. Please stay tuned to future updates for additional information regarding this week's schedule," a notice from Majority Whip Tom Emmer's office said. Speaker Mike Johnson expressed optimism that the Senate's version of the One Big Beautiful Bill will pass in the GOP-led House despite opposition from moderates and conservatives. "We're going to pass this bill one way or the other," Johnson said leaving the Capitol Monday evening. "And I have prevailed upon my Senate colleagues to please, please, please, put it as close to the House product as possible. I have been very consistent from the very beginning. Johnson did not rule out passing the Senate version as is and said, "there's still a lot of amendments, and a lot of game to play." Asked if GOP House leaders would make changes to what the Senate sends over, Johnson said, "We'll see what the final product is. I am very hopeful as always. We will get this job done. We'll see what happens." The speaker did not respond to a question about passing the bill by the Fourth of July deadline. Republican leaders have told members they will receive 48 hours notice before a vote is called and will have 72 hours to review the bill text. The House passed the Trump megabill by just one vote back in May. The Senate version of the bill will face an uphill battle in the House, given the GOP's razor-thin majority.

Several conservatives, including Reps. Chip Roy of Texas, Josh Breechen of Oklahoma and Eric Burlison of Missouri have also expressed opposition to the Senate's version of the bill. Johnson and other Republican leaders worked through the weekend to lock down the votes even as several lawmakers have expressed opposition to the Senate's version, which is still not finalized. Johnson can only afford to lose three defections if all members are voting and present. White House press secretary Karoline Leavitt said President Trump was working "hand in hand" with Johnson and Thune, and that the two leaders had met with him at the White House earlier Monday. "Republicans need to stay tough and unified during the home stretch, and we are counting on them to get the job done," Leavitt said during the White House briefing. But sources familiar with the matter told ABC News Thune and Johnson have not met with President Trump at the White House, and as of now the two leaders have no current plans to meet with the president on Monday as the "One Big Beautiful Bill Act" progresses in the Senate. A spokesman for Thune said he is preoccupied as the Senate moves through amendments to the megabill. "Teams are obviously in close contact/coordination, as always, but we're continuing to move through vote-a-rama in the Senate as we work to move this bill one step closer to the president's desk," the spokesman said in a post on X. Speaker Johnson is in Washington working through House members' concerns as the Senate works through the bill, including several provisions that could spell problems later in the week if the bill is sent back to the House.
