House leaders are postponing their latest effort to block votes on President Donald Trump’s tariffs until 8:30 p.m. amid internal GOP backlash.

House Republican leaders are attempting to use a procedural measure to block any resolutions related to Trump’s tariffs until the end of July, restarting a moratorium on such votes that expired on January 31. But they face significant internal opposition from a band of tariff-skeptical Republicans, led by Reps. Thomas Massie of Kentucky and Rep. Kevin Kiley of California.

Several Republican lawmakers have expressed discomfort with a tariff regime that polling shows is broadly unpopular, even with parts of the GOP base, as Americans continue to grapple with high costs for everyday goods.

House leaders have side-stepped the controversy since last March, when they first used a procedural measure to block efforts to force a vote on the national emergency Trump used to implement the tariffs. The move has guarded members from a controversial vote ahead of a crucial midterm election and has protected the president from clear vote of Congressional disapproval as his administration attempts to strike agreements with major trading partners.

If Republicans fail to pass the new procedural block, Democrats are aiming to force a vote on Trump’s 25 percent tariff on Canadian goods as early as Wednesday, with votes on the president’s global tariffs and tariffs on Brazil and Mexico to follow.

The Senate has already disapproved of the tariffs four times.

House Minority Leader Hakeem Jeffries said Tuesday a GOP counterproposal on Department of Homeland Security funding is “woefully inadequate” and shows the White House “is clearly not open to” several key Democratic demands.

Speaking four days ahead of a DHS shutdown deadline, Jeffries said the Republican offer did not satisfactorily address a need for judicial warrants, detention center standards, independent investigations and excessive-force standards. Asked about whether the Trump administration would support a prohibition on masks for federal agents, Jeffries said, “That’s an open question.”

“They don’t appear to be open to … ensuring that ICE agents are identifiable in a manner consistent with every other law enforcement agency in the country,” Jeffries said.

Also speaking Tuesday morning, Senate Majority Leader John Thune said he believed there was still room for compromise, with support from at least seven Senate Democrats needed for any shutdown-averting stopgap measure.

“There are things I think on probably both sides that are non-negotiables,” he said. “But I do think there are a number of things in the range of common ground.”

Speaking on the Senate floor, Senate Minority Leader Chuck Schumer struck a more cautious tone than Jeffries, saying Democrats “need to see more from Republicans very soon.”

“What Democrats propose is the definition of common sense, he said. “We simply want ICE to follow the same standards that most law enforcement agencies across America already follow.”

Speaker Mike Johnson said in an interview Tuesday he will push ahead an afternoon vote to ban challenges to President Donald Trump’s global tariffs over committed internal GOP opposition.

Language tucked into a procedural measure would forestall votes on privileged resolutions of disapproval through July 31, reviving a ban that expired Jan. 31 as Democrats plan to push fresh tariff votes as soon as Wednesday. But Johnson is facing growing GOP backlash to the move from a band of tariff-skeptical House Republicans.

Two of them, Reps. Kevin Kiley of California and Thomas Massie of Kentucky, told Blue Light News they will oppose the rule — enough to tank the procedural vote if all Democrats vote against it as expected. Rep. Victoria Spartz (R-Ind.) also said she is a “no” on the procedural vote, though she is known to change her mind on the floor.

Inside a closed-door conference meeting Tuesday morning, Johnson told House Republicans he was going ahead with the vote, arguing to members that they needed to wait until the Supreme Court rules on Trump’s tariff powers, according to three people in the room granted anonymity to describe the private meeting. That ruling could comes as late as the end of June.

Majority Leader Steve Scalise declined to say if GOP leaders would have the vote to adopt the blockade language, telling a Blue Light News reporter to “ask the whip questions about vote coalitions.”
