It's a Trump-Democrats immigration standoff: 5 things to watch

Here we go again.

Leaders in Washington are running up against a Jan. 30 deadline to avert a federal shutdown a little more than two months after dragging the country through the longest government closure in its history.

The cause this time is civil unrest in Minneapolis over President Donald Trump's mass deportation plan in the aftermath of two U.S. citizens, Renee Nicole Good and Alex Pretti, being killed by federal immigration officers this month.

That fury quickly made its way to Capitol Hill where Senate Democrats, buoyed by shifting public sentiments, sense Trump and his Republican allies in Congress are on their heels.

Democrats appear mostly united in their vow to use the filibuster to block a $1.2 trillion measure that includes Department of Homeland Security funding unless specific new rules are imposed on Immigration and Customs Enforcement and the U.S. Border Patrol, the two agencies that killed Good and Pretti, respectively.
