Washington —House Republican leaders are scrambling to shore up support for President Trump'smassive domestic policy billamid pushback to the Senate's changes, as the GOP seeks to approve the final version of the legislation ahead of a July 4 deadline to get the bill to the president's desk. As the House met Wednesday to take up the bill, which squeaked through the Senate a day earlier, it remained unclear if Republicans have enough support to get it over the finish line. The House needs to take a key procedural vote before it can move toward final passage, but it's not clear when that vote will take place or if it will pass. Lawmakers remained stuck on a separate vote for over three hours Wednesday afternoon. House Majority Leader Steve Scalise said lawmakers are planning to forge ahead with the procedural vote Wednesday afternoon, but they're waiting for the return of some members whose flights to Washington were delayed. Those members are expected to arrive "shortly," the Louisiana Republican told reporters. Several members on both sides of the aisle had their flights canceled or delayed by bad weather as they raced back to Washington for the vote. All the Democrats appeared to be on hand for proceedings by Wednesday afternoon. Republicans can only afford three defections if all members are present and voting. House GOP leaders are aiming to move ahead quickly on thesignature legislationof Mr. Trump's second-term agenda, which includes ramped-up spending for border security, defense and energy production and extends trillions of dollars in tax cuts, partially offset by substantial cuts to health care and nutrition programs. But some House Republicans, who voted to pass an earlier version of the bill in May, are unhappy with the Senate's changes. Potential holdouts, including moderates and members of the conservative House Freedom Caucus, were meeting with Mr. Trump on Wednesday as the White House puts pressure on House Republicans to get the bill across the finish line, which one lawmaker called "very productive." But GOP Rep. Andy Harris of Maryland, the chairman of the conservative House Freedom Caucus, told reporters that he expected the procedural vote to fail in the afternoon. The House Rules Committee advanced the Senate's changes to the bill overnight, setting up the action on the floor. GOP Reps. Ralph Norman of South Carolina and Chip Roy of Texas joined Democrats on the panel to oppose the rule. Both are among the group of hardliners who are likely to oppose the procedural vote in the full House. "What the Senate did is unconscionable," Norman said. "I'll vote against it here and I'll vote against it on the floor until we get it right." Hours later, Norman returned to the Capitol following a meeting with Mr. Trump and other House Republicans. He described the meeting as "very productive" but didn't say whether he will ultimately vote yes, telling reporters he's still trying to learn more about how the bill will be implemented if it passes. House Speaker Mike Johnson, a Louisiana Republican, has spent weeks pleading with his Senate counterparts not to make any major changes to the version of the bill that passed the lower chamber by a single vote in May. He said the Senate bill's changes "went a little further than many of us would've preferred." The Senate-passed bill includessteeper Medicaid cuts, a higher increase in the debt limit and changes to the House bill's green energy policies and the state and local tax deduction. Other controversial provisions that faced pushback in both chambers, including the sale of public lands in nearly a dozen states, a 10-year moratorium on states regulating artificial intelligence and anexcise taxon the renewable energy industry, were stripped from the Senate bill before heading back to the House. Johnson said Wednesday that "we are working through everybody's issues and making sure that we can secure this vote" amid the opposition. He added that he and the president are working to "convince everybody that this is the very best product that we can produce." "I feel good about where we are and where we're headed," Johnson added. Harris told reporters Wednesday that that the president should call the Senate back into town to come to an agreement on changes to the bill. GOP leaders, however, said the House would vote on the Senate bill "as-is." Should the House make changes to the bill, the revisions would require the Senate's approval, or force the two chambers to go to conference committee to iron out a final product that the two bodies could agree on, jeopardizing the bill's timely passage. Rep. Dusty Johnson, a South Dakota Republican, seemed optimistic after the White House meetings with holdouts Wednesday, saying "Donald Trump is a closer" and adding that "members are moving to yes.""I know there are some members who think they're going to vote no right now," the South Dakota Republican said. "I think when the choice becomes failure or passage, they're going to understand that passage beats the hell out of failing." In a Truth SocialpostWednesday morning, Mr. Trump urged the GOP to get the bill done, saying to his party, "don't let the Radical Left Democrats push you around." "We've got all the cards, and we are going to use them," he said. GOP Rep. Virginia Foxx of North Carolina likewise urged House Republicans to get the bill to the president's desk Wednesday. "President Trump has his pen in hand and is waiting for the House to complete its work," Foxx said. "We've championed this legislation for months, have guided it through the appropriate processes, and now we're on the one-yard line." Meanwhile, with few levers to combat the bill's passage, House Democrats spoke out forcefully against the legislation. "We will not stand by and watch Trump and his billionaire friends destroy this country without putting up one hell of a fight," Democratic Rep. Jim McGovern of Massachusetts said, calling the bill a "massive betrayal of the American people." Jeffries said that "every single House Democrat will vote 'hell no' against this one, big ugly bill," while adding that "all we need are four House Republicans to join us in defense of their constituents who will suffer mightily from this bill." Democratic leaders called out some Republicans by name, including Reps. Rob Bresnahan and Scott Perry of Pennsylvania and Reps. David Valadao and Young Kim of California. "It's unconscionable, it's unacceptable, it's un-American, and House Democrats are committing to you that we're going to do everything in our power to stop it," Jeffries said. "All we need are four Republicans, just four."
