Some of the nation’s busiest airports saw hourslong security lines this weekend, as the partial government shutdown begins to hit air travel. Most checkpoints use federal TSA screeners, who must work without pay during shutdowns. San Francisco International Airport, however, uses a private screening contractor under TSA oversight, which keeps lines moving. Some experts say the model deserves a closer look as a way to protect airport security operations during lapses in funding. But the TSA union warns privatization could cut pay and protections for workers and introduce security risks. Travel industry groups are pushing another solution. They say Congress should pass legislation to keep aviation workers paid during shutdowns.

A bill to fund the Department of Homeland Security is stalling out again in Congress. Republicans invoked the war in Iran and the prospect of retaliatory terrorist attacks as they tried Thursday to pass a bill funding the department. But Democrats blocked the legislation as they insist on changes to immigration enforcement operations. While the House will also take up the bill later Thursday, the vote will be more about putting lawmakers on the record again about where they stand. In the end, a bipartisan compromise will have to be reached to end a DHS shutdown that began Feb. 14.

U.S. Secret Service says an armed man was shot and killed after entering the secure perimeter of Mar-a-Lago, President Donald Trump’s resort in Palm Beach, Florida. Although Trump often spends weekends at his resort, he was at the White House when the breach occurred early Sunday morning. Authorities say the man had a gas can and a shotgun. The FBI says investigators have identified him as 21-year-old Austin Tucker Martin of North Carolina. Investigators have not identified a motive. However, Trump has faced threats to his life before, including two assassination attempts during the 2024 campaign.

The Department of Homeland Security says the Global Entry program shuts down for as long as the partial government shutdown continues. On Sunday, the agency says staffing limits are forcing case-by-case changes at airports. The shutdown starts after a funding fight over the Department of Homeland Security. Democrats also push for changes to immigration operations tied to President Trump’s deportation campaign. Travel gets squeezed as a winter storm hits the East Coast from Sunday into Monday. Many Monday flights out of big Northeast airports get canceled. Global Entry speeds customs for approved travelers and also includes TSA PreCheck, which DHS now keeps running.

Lawmakers and the White House are offering no signs of compromise in their battle over oversight of federal immigration officers. That impasse has led to a pause in funding for the Department of Homeland Security. A partial government shutdown began Saturday after congressional Democrats and President Donald Trump’s team failed to reach a deal on legislation to fund the department through September. Democrats are demanding changes to how immigration operations are conducted after the fatal shootings of two U.S. citizens by federal officers in Minneapolis last month. Congress is on recess until Feb. 23, and both sides appear dug into their positions.
