Republican senators are considering dropping a proposal for $1 billion in security money for the White House complex and President Donald Trump’s ballroom after it has failed to win enough party support on Capitol Hill.

Pressured by the White House, Republicans have tried to add the money to a roughly $70 billion bill to restore funding to U.S. Immigration and Customs Enforcement and the Border Patrol. But the security proposal has met with backlash from some GOP lawmakers who are questioning the cost and the lack of detail from the White House and U.S. Secret Service about how the taxpayer dollars would be used.

Sen. John Kennedy, R-La., said Wednesday that the bill was “back to square one” without the security money because “the votes are not there.”

Sen. Thom Tillis, R-N.C., said the effort to add the security package to the bill was a “bad idea” and he does not think there is enough backing to pass it, even if it were reduced.

The text of the bill has not yet been released. But Senate Majority Leader John Thune, R-S.D., acknowledged “ongoing vote issues” as leaders try to measure Republican support, as well as “ongoing parliamentarian issues” as they try to figure out what will be allowed in the bill under the chamber’s rules.

The wrangling comes as Democrats have criticized Republicans for trying to fund Trump’s ballroom when voters are concerned about basic affordability issues — and as some GOP lawmakers have grown increasingly frustrated with Trump. Several have spoken out against the administration’s $1.776 billion settlement fund designed to compensate Trump’s allies, and many were upset by the president’s endorsement Tuesday of Texas Attorney General Ken Paxton in the party primary runoff next week against Sen. John Cornyn.

“There’s always a consequence with taking on United States senators,” Thune said. Trump “obviously has his favorites and people he wants to endorse and that’s his prerogative. But what we have to deal with up here is moving the agenda, and obviously that can become slightly more complicated.”

Republican opposition blocks Secret Service request

Under the Secret Service request, about $220 million would pay for security improvements related to the ballroom. The rest would go for a new screening center for visitors, training and other security measures.

Tillis said the bill should not have included the other security improvements “because it’s just giving everybody the ‘billion-dollar ballroom.’”

“They need to explain to me why we need this,” Tillis said, noting that Trump had originally said private money would cover the project.

Several other Republicans in the House and Senate have questioned the request, and senators left a briefing with the director of the Secret Service last week saying they needed a lot more information.

People “can’t afford groceries and gasoline and healthcare, and we’re going to do a billion dollars for a ballroom?” asked Louisiana Sen. Bill Cassidy, who lost reelection in the GOP primary on Saturday after Trump endorsed one of his opponents.

Sen. Jim Justice, R-W.Va., said he is supportive of the security money and thinks it is necessary to protect the president. But he acknowledged that the optics are not very good for Republicans, and that they have not communicated about it well.

“We’ve got people out there who are worried about how in the world they’re going to have enough gas to get home,” Justice said.

As Republicans challenged parts of his agenda, Trump unloaded on the Senate in a social media post.

He urged Republicans to fire the Senate parliamentarian, Elizabeth MacDonough, who said over the weekend that parts of the $1 billion security proposal cannot remain in the ICE and Border Patrol bill. Trump renewed his long-standing calls for the Senate to pass the SAVE Act, a Republican bill that would require all voters to prove U.S. citizenship, and to end the Senate filibuster.

“Republicans play a very soft game compared to the Dumocrats,” he wrote. “It is their single biggest disadvantage in politics.”
