WASHINGTON — The White House warned Congress on Tuesday that money used to pay Department of Homeland Security personnel through executive actions will be exhausted by May and called on the House to quickly approve a budget resolution. In a memo late Tuesday, the Office of Management and Budget said funds tapped by President Donald Trump to pay Transportation Security Administration and other DHS workers are running out.

"DHS will soon run out of critical operating funds, placing essential personnel and operations at risk," the memo said. The memo urged the House to approve the budget resolution that the Senate passed in an all-night session last week, a step intended to pave the way for full funding for DHS. The Senate launched the budget resolution process last week and is waiting for the House to act. Once the resolution is approved, the House and Senate are expected to draft the actual Homeland Security funding bill.

DHS has been operating without regular funds for more than two months, marking the department's longest lapse in regular funding. Department salaries total more than $1.6 billion every two weeks. Workers, including TSA employees, have relied on executive actions by Trump to ensure their paychecks. DHS Secretary Markwayne Mullin said in a recent statement that the department's operating funds are drying up.

House and Senate Republicans pursued a strategy to approve funds for Immigration and Customs Enforcement and Border Patrol without Democratic support. They want to provide $70 billion for ICE and Border Patrol operations for the remainder of Trump's term to avoid interruptions in funding. Democrats refused to fund ICE and Border Patrol without changes to those operations after the deaths of Americans protesting Trump's deportation agenda. Congress approved about $170 billion through Trump's tax cuts bill last year to pay immigration enforcement workers.

House Speaker Mike Johnson is expected to consider legislation this week to fund other parts of DHS, including the TSA, the Coast Guard and other agencies. A bipartisan Homeland Security funding bill passed the Senate a month ago after Republicans agreed to carve out immigration-related funds that Democrats had opposed.
