Senate Republicans are abandoning critical border security and immigration enforcement funding, instead choosing to snub President Donald Trump over perceived political disagreements. Senate Majority Leader John Thune (R-S.D.) reportedly told senators Thursday to head home on recess until June. When asked if Republican senators are “responding to politics,” including Trump’s successful primary campaign to oust Senator Bill Cassidy (R-La.) and the president’s endorsement of Texas Attorney General Ken Paxton (R) over longtime Senator John Cornyn (R-Texas) in the Lone Star State’s GOP Senate primary, Thune is said to have responded, “It’s hard to divorce anything that happens here from what’s happening in [the] political atmosphere around us,” adding, “You can’t disconnect those things.”

Another point of contention between the White House and Senate Republicans is Trump’s plan to establish a $1.776 billion “Anti-Weaponization Fund” to compensate victims of government weaponization. “I think it’s stupid on stilts,” said outgoing Senator Thom Tillis (R-N.C.) of the planned fund. “It will invariably put us in a position where your taxpayer dollars and my taxpayer dollars could potentially compensate someone who assaulted a police officer” at the January 6, 2021 Capitol Building protest. Tillis added, “When you take money from me to give to a purpose I vehemently disagree with, that’s tyranny, and that’s what that account is.”

Senate Republicans had agreed with Trump on a June 1 deadline for passing the $72 billion immigration enforcement funding bill, but rankled at the prospect of approving the Anti-Weaponization Fund, instead planned to install heavy restrictions on the fund and its use in the bill — with some reports claiming that the president threatened to veto any bill containing such restrictions. (The White House has denied making any such threat.)

The senators’ departure from Washington, D.C. means that the June 1 deadline will almost certainly not be met, but Semafor reported that the Trump administration is still certain that the president’s agenda will succeed in the Senate. “No one should be doubting how he’s able to bend everything to his will,” one unnamed White House official said of Trump’s sway over the GOP, adding that the president has “shown that he can wield” his influence “in many different ways.” According to Semafor, a number of GOP senators — including Cassidy, Thune, Tillis, Chuck Grassley (Iowa), and Mitch McConnell (Ky.), among others — insisted that the White House “consult more closely” with Congress before making decisions.

A delay in the Senate on the funding bill means a likely delay in the House of Representatives, where Republicans have been quicker to approve the president’s agenda, particularly on immigration issues. House Freedom Caucus Chairman Rep. Andy Harris (R-Md.) suggested that Trump’s June 1 deadline would likely not be met but pledged to approve the funding as soon as possible. “The fact of the matter is, if the Senate can’t do its job on time, then we’ll have to take care of it when we come back,” Harris observed.

While House leaders have indicated a willingness to vote on the legislation prior to the Memorial Day weekend, the Senate Budget Committee has not released the text of the bill, nor has the committee voted on that text, according to insiders. With no movement on the Senate side, House Republicans are preparing to leave town for recess as well.

Senate Republicans have been taking heat over the last several months, as the SAVE America Act, approved by the House early in February, has stalled. The Senate failed to pass a prior version of the bill, the Safeguard American Voter Eligibility (SAVE) Act, last year. The legislation is broadly popular, even among Democratic voters, and would require proof of U.S. citizenship when registering to vote and photo identification when voting. Thune and other Senate Republicans have indicated that the bill will not be approved, and it has languished in the Senate for nearly four months.
