WASHINGTON >> President Donald Trump will look to build momentum for his sweeping tax cut and immigration bill on Tuesday, taking a trip to Capitol Hill to address House Republicans as they try to work out their differences before a planned floor vote later this week.

Trump will attend the GOP’s weekly conference meeting, according to a White House official who spoke on condition of anonymity to discuss plans not yet made public.

Republicans can afford only a few defections to get the bill through the House, and it’s clear differences remain. Some deficit hawks are insisting on quicker cuts to Medicaid and green energy programs before giving their full support. Others are seeking a large increase in the state and local tax deduction.

Trump has been pushing hard for Republicans to unite behind the bill, which would enact many of his campaign promises. The bill carries his preferred title, the “ One Big Beautiful Bill Act.”

House Republicans narrowly advanced the sprawling 1,116-page package in a rare weekend vote late Sunday, but just barely, as GOP leaders promise more negotiations ahead.

Republicans criticizing the measure argued that the bill’s new spending and tax cuts are front-loaded in the bill, while the measures to offset the cost are back-loaded. In particular, they are looking to speed up the new work requirements that Republicans want to enact for able-bodied participants in Medicaid. They also want to more quickly end tax breaks for green energy projects being used nationwide.

Majority Leader Steve Scalise said on CNBC Monday that work requirements for some Medicaid beneficiaries would begin in early 2027, a big change from the 2029 start date that is currently in the bill.

Late last week, the House Budget Committee failed to advance the package when four conservative Republicans objected. But it was able to do so Sunday on a vote of 17-16, with the four hold-outs voting “present” to allow it to move ahead, as talks continue.

Democrats have decried the cuts Republicans are proposing to Medicaid and food stamps to offset the costs of the tax breaks. Democratic leader Hakeem Jeffries noted that the House Rules committee would begin taking up the measure at 1 a.m. Wednesday.

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