() President Donald Trump is expected on Capitol Hill on Tuesday to try and jolt his “big, beautiful bill” past the finish line.

Trump will address the House Republican Conference Meeting in hopes of unifying lawmakers behind his 1,100-page proposal. The bill would extend tax cuts, beef up border security and raise defense spending. It would also cut funding for Medicaid, food stamps and green energy programs.

“If Democrats get their way and the Trump tax cuts are not extended, Americans will face the largest tax hike in history, to the tune of $4 trillion. Republicans must not side with Democrats in helping them raise taxes,” said White House press secretary Karoline Leavitt.

Trump is looking to unify his party behind his domestic agenda, but parts of the bill have faced intense debate in the House.

Some Republican lawmakers, such as Rep. Chip Roy, R-Texas, have concerns about the budget. They worry tax cuts and new spending are front-loaded in the bill, while measures to offset costs are backloaded.

Roy has also said more needs to be removed from programs related to the Green New Deal, while more centrist Republicans have shared concerns over cuts to Medicaid and food assistance programs.

Democrats have sought to unite against the bill and criticized Trump’s budget and its unusual late-night advancement through the House Budget Committee on Sunday.

“They literally are trying to take health care away from millions of Americans at this very moment in the dead of night,” said House Democratic Leader Hakeem Jeffries of New York.

The bill’s next stop is the House Rules Committee, which is scheduled to examine the proposal and make last-minute changes later this week.

Republicans will need just about every vote they can get to pass this cornerstone piece of Trump’s agenda.

Speaker Mike Johnson said he wants to get the bill on the president’s desk by the Fourth of July.
