Trump says he's 'pretty much not happy' with any deal to reopen DHS as negotiations continue

As Senate Republicans on Tuesday scrambled to strike a deal to fund the Department of Homeland Security amid the agency's partial shutdown, President Donald Trump said he would not be happy with any deal they hammered out, remaining noncommittal on if he would sign anything.

Senate Democrats aren't committing to supporting the GOP proposal, either.

"Well, I don't want to comment until I see the deal, but as you know, they're negotiating a deal. I guess they're getting fairly close. But I think any deal they make, I'm -- I'm pretty much not happy with it,” Trump told reporters in the Oval Office. He was asked if he would support a deal garnering Republican support that would fund everything in DHS except Immigration and Customs Enforcement operations.

When asked if he would be "comfortable with a deal that involves separating ICE funding from the DHS funding package" to reopen the agency, Trump deflected and said a deal was being worked on.

“Well, they're working on all of that. You know, that's a detail that they'll explain later,” Trump said, as the department's shutdown stretches into its 39th day.

This comes despite a White House official saying earlier Tuesday that "conversations are ongoing but this deal seems to be acceptable."

Senate Majority Leader John Thune said earlier Tuesday that Republicans were moving ahead in the Senate with a proposal to fund DHS -- except for immigration enforcement operations -- for the rest of the fiscal year.

"It's basically the discussion that's been held for the last couple days. I think the offer originally with the Democrats, and that is to fund 94% of the DHS budget, the $5.5 billion that was, as part of the ICE budget, that was pre-funded by reconciliation, would not be included in this deal,” Thune explained to reporters.

Senate Minority Leader Chuck Schumer and Democratic leaders are not committing to supporting this new GOP proposal -- noteworthy because Democrats, for weeks, have demanded stripping out ICE funding while approving appropriations for other agencies inside DHS like such as Transportation Security Administration, Cybersecurity and Infrastructure Security Agency, Federal Emergency Management Agency, Secret Service and the Coast Guard.

ICE has money to continue its operations, following a $75 billion cash infusion over five years in the “One Big Beautiful Bill Act” that President Donald Trump signed into law last summer. ICE agents continue to be paid, while their other DHS colleagues are not.

Democrats are blocking DHS funding and demanding ICE reforms following the shootings of Renee Good and Alex Pretti by federal law enforcement in Minneapolis. Schumer now says Democrats are pursuing additional negotiations on ICE reforms and that the piecemeal approach to funding DHS should also include immigration enforcement reforms.

“We need reforms to ICE. We need to rein in the violence. We have never changed our position. This does not have any reforms in ICE," Schumer said Tuesday. "We'll be sending them an offer back, and I can assure you, it'll contain significant reform in it."

Senate Republicans say they’re running out of concessions to offer.

"It's essentially what the Democrats have been asking for. And so we're going to have an opportunity to vote on that," Thune told reporters.

It's not yet clear how any emerging deal factors in to Trump's demand over the weekend that Republican not make a deal with Democrats on DHS funding without also passing his voting and gender-affirming care legislation, the SAVE America Act.

The legislation would restrict mail-in ballots, require photo ID at polling places and mandate that states obtain proof of citizenship before registering a person to vote in a federal election. Trump has tacked additional provisions onto the list of things he would like to see in the law: banning transgender women from playing in women’s sports and gender-affirming surgeries for minors.

SAVE America Act provisions could also be included in a future reconciliation bill, although nothing is set in stone, and the legislation may not meet strict budget rules to be included in a reconciliation package.

Pressure on lawmakers is mounting as lines grow at airports across the country and tens of thousands of workers, including TSA officers, go without pay. Senators continue to get paid.

ICE agents sent by Trump are now stationed at more than a dozen airports across the nation to assume some of the duties of TSA officers affected by the partial shutdown.

While these recent developments mark the most progress on a DHS funding deal in weeks, it's still a long way from a done deal. Even if the Senate agrees on a deal and passes it, it would still need to go back to the House.
