Congress approved a spending package Tuesday afternoon that secures funding for the vast majority of federal agencies through September, ending the second government shutdown in the span of four months.

But what’s left unfinished — funding for the Department of Homeland Security — will be a doozy, with partisan tensions over President Donald Trump’s immigration enforcement agenda threatening another lapse for the embattled department that also includes TSA, FEMA and other crucial agencies.

The package the House passed in a bipartisan 217-214 vote Tuesday afternoon only funds DHS through next week. Democrats are refusing to support months of additional cash until Republicans agree to rein in the actions of ICE and Border Patrol agents following the fatal shootings last month of two U.S. citizens in Minnesota.

If Republicans don’t concede to enacting significant new mandates for DHS by the new Feb. 13 deadline, the department many Democrats have called “rogue” will face another funding lapse or short-term patch.

“We have a list that we want done, and we aren’t settling for half-measures,” Rep. Pete Aguilar (D-Calif.), the No. 3 party leader, told reporters Tuesday. He warned that if Senate Majority Leader John Thune and Speaker Mike Johnson “don’t want to come to the table and negotiate real reform, then they’re going to have to explain to the American public why they’re shutting down agencies.”

Trump is expected to swiftly sign the legislation, ending the partial government shutdown that began early Saturday morning after the Senate passed the altered package, punting the measure back to the House.

By advancing the trillion-dollar package, Congress has approved more than 95 percent of the government funding it approves each year to run federal agencies, after clearing full funding for some agencies in November and another slate in January.

Under the legislation that now awaits the president’s signature, the Pentagon and all remaining domestic agencies besides DHS will get new funding levels through the end of the fiscal year, which started with the longest government shutdown in U.S. history.

“We finalized true, bipartisan, bicameral bills to fully fund our government in a member driven, district focused way,” House Appropriations Chair Tom Cole (R-Okla.) said on the House floor. “Funding the government is not an optional exercise. It’s the most basic duty we have in Congress.”

Only 21 Democrats voted yes on passage, highlighting the challenge leaders face over the next 10 days in negotiating new immigration enforcement rules that can attract enough Democratic support for funding DHS into the fall.

“I refuse to send another cent to Stephen Miller or Kristi Noem,” Rep. Jim McGovern (D-Mass.) said this week. “They are undermining our Constitution, and the department they run is murdering American citizens in the streets.”

To ensure Democratic leaders on both sides of the Capitol are aligned heading into negotiations with Republicans over changes to DHS immigration operations, Jeffries is set to meet Tuesday afternoon with Senate Minority Leader Chuck Schumer.

House Democrats are demanding that Jeffries have a seat at the bargaining table after many groused this week about the altered funding package Senate Democrats brokered with the White House.

“They need to talk to Hakeem — the House and Senate are equal partners,” Rep. Debbie Dingell (D-Mich.) said in an interview.

House Democrats contend that they have a better understanding of Trump’s immigration enforcement actions in communities throughout the country, as well as the sentiment of Americans.

“We are the ones that are closest to the anger and the frustration of our constituents,” Rep. Pramila Jayapal (D-Wash.) said in an interview. “We need [Senate Democrats] to start negotiating with us and carrying out our demands instead of constantly caving to Republicans.”

Senate Majority Leader John Thune said in an interview Tuesday he has made no decisions about bypassing Senate filibuster rules to skirt the normal 60-vote margin required to advance legislation in the chamber.

Rep. Anna Paulina Luna (R-Fla.) said Monday she had White House-brokered “assurances” that the Senate would allow for a “standing” or “talking” filibuster that could allow the SAVE Act, a House-passed elections bill pushed by conservative hard-liners, to be enacted into law.

Thune was not party to Luna’s conversation with President Donald Trump, which prompted Luna to indicate she would support a massive spending bill moving through the House on Tuesday. Many GOP senators have long opposed weakening the 60-vote margin, believing it would open the door to far-reaching Democratic policies.

“Some of our colleagues in the Senate are interested in it,” Thune said. “We will have a conversation about it. Nothing decided.”

Speaker Mike Johnson said in an interview Tuesday morning that Republicans have given Bill and Hillary Clinton a noon deadline Tuesday to provide details of how they plan to comply with a pair of subpoenas issued by the House Oversight and Government Reform Committee, which have until this point gone unheeded.

Otherwise, Johnson said, Republicans will move forward with votes later this week to hold the former president and secretary of state in criminal contempt of Congress.

“We’re holding off until noon,” Johnson said. “They have a deadline until noon to work out the details, and if it’s not done satisfactorily, then we’ll proceed with the contempt.”

Majority Leader Steve Scalise also said in an interview that, if the details aren’t provided, then Republicans will proceed with a vote Wednesday as leadership had initially intended before the Clintons surprised Capitol Hill by reversing course. They had for months been resisting subpoenas to testify in the House Oversight investigation into the convicted sex offender Jeffrey Epstein, saying the process was invalid and designed to embarrass and put them in prison.

According to a person granted anonymity to share internal discussions between the Oversight Committee and the Clintons’ legal team, the GOP-led panel is seeking clarification that the Clintons will accept the standard deposition terms for which they were originally subpoenaed. That includes transcribed, filmed depositions to take place in February, with no time limits.
