The United States Senate packed up and left Washington this week without finishing the reconciliation bill that carries funding for ICE and Border Patrol, walking away from the centerpiece of President Donald Trump's domestic agenda just as a bitter Texas primary fight exposed fault lines inside the Republican conference. Senate Majority Leader John Thune told senators in the room that the chamber would not return until June, as Breitbart News reported, leaving border-security money and the broader spending package in limbo.
Punchbowl News founder Jake Sherman broke the news on X, writing that the Senate was going home "all because of the DOJ weaponization fund." The House, he added, was expected to follow suit soon.
Republican senators publicly pointed to substantive disputes over the bill. But Thune himself acknowledged a different force at work, the political shockwave from Trump's endorsement of Texas Attorney General Ken Paxton over incumbent Sen. John Cornyn in the May 26 Republican primary runoff.
When Punchbowl News senior reporter Brendan Pedersen asked Thune whether Senate Republicans were responding to politics, specifically, Trump endorsements and snubs that week, the majority leader did not deny it.
"It's hard to divorce anything that happens here from what's happening in political atmosphere around us. You can't disconnect those things."
That candid admission landed hard. The Senate had been expected to press forward on the reconciliation package, which funds ICE and Border Patrol operations. Instead, senators chose an early recess, a decision that delays action on border security, immigration enforcement, and the Save America Act provisions Trump has demanded.
The timing looks worse when you consider that Senate Republicans had already advanced the reconciliation bill to fund ICE and Border Patrol through 2029. That earlier momentum now stalls while senators scatter to their home states.
On May 19, Trump announced his "Complete and Total Endorsement" of Ken Paxton, calling him "The Highly Respected Attorney General of Texas," "an America First Patriot," and "someone who has always been extremely loyal." Trump highlighted Paxton's support for terminating the filibuster and for the Save America Act, two items the Senate GOP conference has struggled to deliver.
Trump described Cornyn as "a good man" who "worked well" in some respects, but added bluntly that the senator "was not supportive of me when times were tough" and came around "very late" to his run for the Republican nomination and presidency, which Trump called "historic."
Vice President JD Vance reinforced the message the same day. Speaking to Breitbart News White House Correspondent Nick Gilbertson, Vance said Paxton would be the "better senator" and explained why the endorsement went the way it did:
"I've known John Cornyn for a long time, but unfortunately, you know, when it really counted, Ken Paxton was there for the country, was there for the president, and that's why he ultimately earned the president's endorsement."
Vance went further, framing the endorsement as a warning to every Republican senator thinking about the next cycle.
"I think the message that people should take from this is, fundamentally, you have got to serve the people who sent you. If you don't do that, you're going to find yourself out of step with voters, or out of step with the President of the United States, and that's not a good place to be politically."
That quote drew a reaction inside the Senate itself. Punchbowl News senior congressional reporter Andrew Desiderio posted that some GOP senators were discussing Vance's remarks and took issue with the suggestion that Cornyn was not there for Trump "when it really counted." Desiderio noted that Cornyn served as the GOP whip during the first two years of the first Trump administration, the period that produced Supreme Court nominations and the Tax Cuts and Jobs Act.
The early departure did not happen spontaneously. A May 18 report revealed that Sen. Thom Tillis of North Carolina told colleagues "in unequivocal terms" that he would not support taking up the reconciliation package that week. Tillis's reasoning was openly political: he warned that Cornyn should be "free to campaign in Texas this week instead of being in D.C. for votes."
In other words, at least one Republican senator explicitly prioritized a colleague's primary campaign over advancing ICE and border funding. Tillis did not frame his objection around policy substance or legislative text. He framed it around giving Cornyn time to campaign.
That kind of maneuvering is exactly what frustrates voters who sent a Republican majority to Washington expecting results on border security. The Senate had already passed a budget resolution in an overnight marathon to clear the path for this very funding. Now the path leads to an empty chamber and a locked door until June.
On May 20, Paxton appeared on Fox News and did not mince words about the Republican Senate's record on Trump's priorities:
"The MAGA agenda is dead under John Cornyn. He kills it every time, just like the Republican Senate that he's part of. That's what they're doing. They're killing it."
Rep. Wesley Hunt of Texas, who finished third in the March 3 primary and did not advance to the runoff, endorsed Paxton after Trump did. Hunt said Trump "is fully backing Attorney General Ken Paxton, and SO AM I," called Paxton "the next United States Senator from Texas," and urged his nearly 300,000 supporters to unite behind the attorney general's campaign.
Hunt's endorsement carried an edge. On primary night, Alex Latcham, executive director of the Cornyn-Thune-aligned Senate Leadership Fund, had dismissed Hunt's third-place showing as "abysmal" and called his campaign a "career-ending vanity tour." Hunt's decision to back Paxton rather than Cornyn after that treatment tells its own story about where establishment Republican loyalty gets you.
The pattern here is familiar. Cornyn's allies belittled a fellow Republican on primary night. Now that Republican has thrown his weight, and his voter base, behind Cornyn's opponent. The establishment insult machine tends to produce exactly the coalitions it fears most.
What makes the Senate's early departure so galling is the substance left on the table. The reconciliation bill carries funding for ICE enforcement and Border Patrol operations, the operational backbone of Trump's immigration agenda. Every week that funding sits unfinished is a week the agencies tasked with border security and interior enforcement operate without the resources the president has requested.
This is not the first time Senate Republicans have struggled to deliver on these priorities. Earlier this year, Senate Republicans sided with Democrats to sink a SAVE Act amendment during a late-night vote, a move that drew sharp criticism from conservatives who saw it as a betrayal of election integrity commitments. Meanwhile, forty House Republicans moved to block Senate bills until the SAVE Act advanced, reflecting the depth of frustration on the right with the upper chamber's pace and priorities.
Cornyn himself has drawn scrutiny for inconsistency on procedural tactics. He pledged "whatever it takes" on the filibuster in a morning op-ed only to backtrack by 10 a.m. the same day, a reversal that undercut his credibility with voters who want Senate Republicans to use every available tool to pass Trump's agenda.
The Texas Senate Republican primary runoff is scheduled for May 26. The Senate is not expected back until June. The reconciliation bill remains unfinished. And the political temperature inside the GOP conference is higher than it has been in months.
Thune's admission, that the political atmosphere around Trump's endorsements and the Texas race cannot be separated from what happens on the Senate floor, is the most honest thing any Republican leader has said about this episode. It is also the most damning. It means the Senate majority leader knows his conference left town not because the bill was unready, but because the politics were too hot to handle.
Trump endorsed Paxton because he wants a Senate that fights for the agenda voters elected him to deliver. The Senate responded by going home. If Republican senators want to know why voters keep backing outsiders and challengers, they might start by looking at the empty chamber they left behind.
