WASHINGTON — House and Senate Republican leaders jointly announced a plan Wednesday that they said would end the shutdown of the Department of Homeland Security that caused major airport delays.

“In the coming days, Republicans in the Senate and House will be following through on the President’s directive by fully funding the entire Department of Homeland Security on two parallel tracks: through the appropriations process and through the reconciliation process,” House Speaker Mike Johnson, R-La., and Senate Majority Leader John Thune, R-S.D., said in a statement.

The two leaders were vague about the exact plan, but it appears to closely resemble the Senate’s preferred path from Friday.

Johnson and Thune heavily implied that it would be for the Senate to, once again, pass a bill it approved unanimously last week, which it could try to do as early as Thursday.

It would fund all of DHS except ICE and Customs and Border Protection, which Democrats won’t agree to fund without reforms to immigration enforcement operations. Those two agencies already have separate funding.

House Republican leaders trashed that bill and rejected it Friday, but they now appear ready to back down and accept the Senate plan. They would have to vote to pass it through the House.

GOP leadership had no immediate comment on the timing for a vote. Both chambers are scheduled to be on recess until April 13.

Then Republicans would fund ICE and CBP in a separate party-line “budget reconciliation” bill that could bypass a filibuster and get approved without any Democratic votes. The timing for that is even less clear.

Johnson and Thune said the “two-track” plan would “fully reopen the Department, make sure all federal workers are paid, and specifically fund immigration enforcement and border security for the next three years so that those law-enforcement activities can continue uninhibited.”

A White House official told NBC News that the administration supports the Johnson-Thune plan.

Earlier Wednesday, President Donald Trump called on Republicans to pass the party-line bill “no later than June 1st.” He threw the earlier plans to reopen DHS into chaos last week when he declined to comment on the Senate bill, which led House Republicans to reject it.

DHS has been shut down for more than a month, with employees for the TSA, FEMA and other agencies going for weeks without pay. Trump signed an executive order last week to pay TSA employees, but the legality and length of that plan are murky. Thousands of civilian Coast Guard employees and other DHS workers are still not being paid.

Senate Minority Leader Chuck Schumer, D-N.Y., slammed Republicans for having “derailed a bipartisan agreement” for days, “making American families pay the price for their dysfunction.”

“Throughout this fight, Senate Democrats never wavered. We were clear from the start: fund critical security, protect Americans, and no blank check for reckless ICE and Border Patrol enforcement,” he said Wednesday. “We were united, held the line, and refused to let Republican chaos win.”

On Friday, House Minority Leader Hakeem Jeffries, D-N.Y., said, “House Democrats are prepared to support the bill to end the Trump-Republican shutdown of the Department of Homeland Security, make sure TSA agents are paid, stand up for FEMA and for the Coast Guard, for our cyber security professionals, and stop inconveniencing Americans.”
