The White House on Tuesday released a letter detailing changes it is willing to make to the Department of Homeland Security as it looks to secure a deal with Democrats to end the nearly five-week long partial government shutdown.

The move is the Trump administration’s attempt to show it is making a good faith effort after Democrats derided their proposal as unserious and comes as staffing issues at the Transportation Security Administration grow more acute — leading to longer wait times at airports across the country.

The White House, in five points, said it was willing to codify a number of policy changes, including an expansion of the use of body cameras for federal immigration agents; the limit of enforcement in certain sensitive locations, including hospitals and schools; greater oversight of DHS detention facilities; the enforcement of visible officer identification and the adherence to existing law prohibiting the deportation or detention of U.S. citizens.

“We feel that this offer is serious — that it is a good faith attempt to continue to try to come to a reasonable and expeditious conclusion to the shutdown, which we are now seeing is becoming ever more disruptive on Americans’ travel plans, as well as the security mission at the department,” said a senior White House official granted anonymity to describe the private talks.

The White House offer includes some public safety exceptions for the policy changes. For sensitive locations, there is a carve-out for “national security, flight risks and public safety,” and undercover officers would not have to display identification. Undercover officers would also not be required to wear body cameras.

The proposal also doesn’t address two of Democrats main concerns: requiring officials to obtain a judicial warrant before entering private property and prohibiting federal agents from wearing masks. Administration officials have previously said the warrants are a redline.

“We’re trying to move a little bit, but they’ve got to get serious. They are not getting serious,” Senate Minority Leader Chuck Schumer said Tuesday. “The key issues of warrants when you bust in someone’s house. The key issue of identity, of police and no masks. They haven’t budged on that.”

Spokespeople for Schumer did not immediately respond to a request for comment on the White House letter.

It’s the first time in the monthslong negotiation that the White House has released details about its proposal. Republicans have been eager for the White House to share details of its offers to validate their view that the administration had moved toward Democrats on some issues.

The White House letter argued that the majority of Democrats’ demands would “make it impossible to fully protect American citizens from dangerous criminal aliens and expose law enforcement and their families to increasing threats of violence.”

The senior White House official said that at this time, there are no plans for President Donald Trump to meet with Schumer or Democrats to discuss the impasse. The president has tapped border czar Tom Homan — who co-signed the letter with James Braid, the White House director of the Office of Legislative Affairs — to take the lead on working on the policy changes to end the government shutdown.

“There are a lot of technical issues that have to be worked out” for a White House meeting to be a “productive exercise,” the senior official said. “Although, of course, the president is going to make that decision, and at any time, that could be something that does occur.”

Threats from some hard-right House Republicans to block any Senate bill until the SAVE America Act passes appear to be falling flat.

A bill from Sen. Joni Ernst (R-Iowa) to reauthorize small business grant programs passed 345-41 Tuesday, a day after another Senate bill, aimed at recovering Nazi-looted art, passed on a voice vote.

Republicans lawmakers are hoping that Sen. Markwayne Mullin will rescue the Department of Homeland Security from tumult they felt under outgoing Secretary Kristi Noem — and looking for assurances of that at his confirmation hearing Wednesday.

While Mullin is widely expected to be confirmed, the hearing will be an opportunity for Republicans to hammer home the need to fund DHS as a partial government shutdown enters its fifth week. It will also be a chance for Democrats to press the Oklahoma Republican on any changes he may push to make with the Trump administration’s sweeping crackdown on unauthorized immigration — an approach that an increasing number of Americans disapprove of.

Sen. John Kennedy (R-La.), whose questions helped accelerate Trump’s ousting of Noem, said he wants Mullin to show his leadership, particularly in contrast to Noem.

“I want to hear what Markwayne’s thoughts are with respect to FEMA. I want to hear what Markwayne’s thoughts are with respect to getting managerial control of the agency,” Kennedy told reporters Tuesday. “I want to hear Markwayne’s thoughts on getting money to those areas of our country that have been struck by disaster.”

Sen. Cynthia Lummis (R-Wyo.) said she’s hoping for better communication between DHS and Congress, explaining that under Noem’s leadership, it was difficult to get answers from DHS.

“In general, you couldn’t get a return phone call from the Department of Homeland Security on anything. And that’s never been the case with any other agency,” Lummis told reporters last week. “So that was a surprising faux pas.”

After President Donald Trump said he would nominate the first-term Oklahoma senator, Republicans hailed the move, with some openly saying a change was needed from Noem’s divisive and controversy-filled tenure atop the department.

Mullin already enjoys the support of some of Noem’s biggest GOP critics — including Sens. Thom Tillis of North Carolina and Lisa Murkowski of Alaska, who both called for Noem’s departure after immigration officers in Minneapolis shot and killed two American citizens in January.

Murkowski told reporters Tuesday that Mullin is “pretty conservative,” but added that Mullin has a good sense of “the temperature of Congress and what can and cannot happen” and “what people back home are saying.”

But despite his straightforward path to confirmation, Mullin is still likely to come under fire Wednesday.

Questions continue to swirl about Mullin’s investments and businesses, as his wealth has ballooned since entering Congress. He also may have to bury bygones with the chair of the Senate Homeland Security Committee, Sen. Rand Paul (R-Ky.). At a recent fundraiser, Mullin called Paul a “snake” for opposing a minibus funding bill.

Democrats are also skeptical that Mullin will pursue any significant policy changes at DHS — in particular changes they’ve demanded to release funding such as banning officers’ use of masks in the field and requiring more training. Only one Democrat, Sen. John Fetterman (D-Penn.), has committed to voting for Mullin, arguing he’d be a major improvement from Noem.

A number of Democrats are pessimistic that Mullin will handle immigration enforcement differently than Noem given the continued influence of White House deputy chief of staff Stephen Miller, who also serves as Trump’s homeland security adviser, over that brief.

“It’s really Stephen Miller that’s calling the shots there,” said Sen. Andy Kim (D-N.J.), who was one of the Democrats who voted to confirm Noem as DHS chief last year but has said he will not vote for Mullin.

“I don’t trust anybody that’s in that role if Stephen Miller’s just going to continue to dictate what happens,” Kim continued.

Mullin, who has never served on committees with direct oversight of DHS, has largely been in lockstep with the White House on immigration enforcement and other national security issues. He has been seen as an important go-between for both chambers of Congress, as well as between Capitol Hill and the White House during policy discussions.

Mullin notably defended ICE agents after the shootings of two American citizens in Minneapolis by immigration officers, saying “these patriots are doing a difficult job.”

White House spokesperson Abigail Jackson said Mullin will continue the Trump administration’s main objectives at DHS, which have included reversing “Biden’s border crisis” and deporting “countless dangerous criminal illegal aliens.”

“Sen. Mullin is perfectly suited to lead the Department of Homeland Security and work closely with President Trump to continue building on his many successes,” Jackson said.

Ahead of Mullin’s hearing, his boosters are making the case that his experience in the business world will make him an effective manager at the sprawling department, which manages everything from disaster relief, to immigration enforcement, airport security, the Coast Guard and the Secret Service.

Sen. Shelley Moore Capito (R-W.Va.), stressed that background, saying Mullin has “led very successful businesses. He’s led athletic teams” and has been a leader already in the Senate GOP caucus.

Paul and Sen. Gary Peters (D-Mich.), the top Democrat on the Senate Homeland Security and Government Affairs Committee, both declined to offer their thoughts on Mullin before the hearing. Peters, however, assured reporters last week the Oklahoma Republican would face “robust” questions.

Among those planning to press Mullin on his views on immigration is Sen. Richard Blumenthal (D-Conn.). Blumenthal, who has been at the forefront of pushing for changes at Immigration and Customs Enforcement and Border Patrol after the deaths of Alex Pretti and Renee Good in Minneapolis, told reporters Tuesday he hadn’t yet gotten assurances in private meetings with Mullin that the Oklahoma Republican will enact changes at the agency.

“It left me with a very clear impression that he has failed to realize how important reform is and how absolutely necessary change is in that agency,” Blumenthal said of his meeting with Mullin.

Mullin has only been in the Senate for three years, and even his allies acknowledged that he has some gaps in his relationships, given his short tenure to date.

Lummis said Mullin will need to do some outreach to Democrats who have not worked with the lawmaker yet, but praised his energy.

“He bounces off the walls, just in terms of his physical energy levels. He talks fast, and he’s very articulate. He’s great on TV,” Lummis said, adding that leading DHS “probably takes someone with a fairly high amount of energy.”
