President Donald Trump signed a roughly $1.2 trillion funding package Tuesday, putting an end to the brief partial government shutdown that kicked off over the weekend. But before anyone breaks out the champagne, there's a catch: Congress just set up what might be an even messier fight over immigration enforcement and the Department of Homeland Security.

One Department Left Behind

The bill funds 11 annual appropriations bills through September 30, which sounds great until you notice the glaring exception. According to the Associated Press, the Department of Homeland Security only gets money through February 13. That's right, 10 days from now.

Why the short leash? Democrats are demanding changes after federal agents fatally shot two American citizens, Alex Pretti and Renee Good, in Minneapolis last month. House Democratic Leader Hakeem Jeffries made it crystal clear: his caucus won't support any more stopgap funding "without substantial changes" to how Immigration and Customs Enforcement and Customs and Border Protection operate. So negotiators now have a frantic 10-day window to strike a DHS deal, or face a department-only shutdown later this month.

Razor-Thin Margins on Full Display

The House passed the funding package 217-214 earlier Tuesday, but getting there required some serious drama. Republicans first had to pass a procedural rule vote that ended 217-215, with zero help from Democrats. The vote was supposed to happen Monday, but Democrats privately signaled they wouldn't provide votes to fast-track the package, forcing a delay.

Then things got interesting. Leaders held the vote open after Rep. John Rose unexpectedly joined Rep. Thomas Massie in opposition. Rose, who's been complaining that the Senate is dragging its feet on the SAVE Act requiring proof of citizenship to vote, eventually flipped to "yes." That gave Speaker Mike Johnson just enough support to proceed, showcasing just how precarious the GOP's majority really is.

Everyone's a Winner, Apparently

Both parties are claiming victory on the broader package. Republicans avoided the giant year-end "omnibus" bill they blame for runaway spending. Democrats, meanwhile, beat back some of Trump's deepest proposed cuts and added language preventing agencies from quietly redirecting money away from programs Congress actually approved.

Trump called the measure "a great victory for the American people." But the final vote told a more complicated story: 21 Republicans joined most Democrats in voting no, while 21 Democrats crossed over to support it. Johnson needed near-unanimous Republican backing to get it across the finish line.

Markets Shrug

U.S. stock futures barely blinked at the shutdown's end. Shortly after 8 p.m. ET Tuesday, futures tied to the S&P 500 and Dow Jones Industrial Average gained about 0.01% and 0.03%, respectively. Futures tied to the Nasdaq edged lower by over 12 points, or less than 0.05%. Apparently, investors are taking Washington's latest crisis in stride.
