It's time to shut up or shut down for President Donald Trump and Congress.

But first: Defense Secretary Jim Mattis is retiring, Trump said Thursday, one day after Trump said he would pull U.S. troops out of Syria — a move Mattis advised against.

Border wall funding, or lights out

One bid to ward off a partial government shutdown collapsed Thursday when President Donald Trump refused to sign a Senate-backed bill because he wanted more money for his border wall. The short-term spending bill punts a decision over border wall funding until next year when a newly Democrat-controlled House won't likely see it through. Funding to keep multiple agencies and departments open will lapse at midnight Friday unless Congress and the White House reach a deal.

So what happens if a shutdown occurs? National parks, law enforcement training and federally assisted loans could all be affected — plus 420,000 federal employees including border patrol agents. And speaking of the border ...

A ban on asylum-seekers in the U.S.

Others note that despite Trump's claim that "we won" against ISIS, America's involvement in Syria remains nearly a complete failure.
