President Donald Trump threatened to veto a spending bill that he promised to sign, putting the United States on a path to the second government shutdown of his term.

White House budget director Mick Mulvaney said Thursday the president would sign the $1.3 billion omnibus spending bill passed by the U.S. House of Representatives, and Trump must sign it by midnight Friday to avert a shutdown.

“Let's cut right to the chase," Mulvaney said. "Is the president going to sign the bill? The answer is yes.”

But Trump threatened to blow it up Friday morning in a tweet.

"I am considering a VETO of the Omnibus Spending Bill based on the fact that the 800,000 plus DACA recipients have been totally abandoned by the Democrats (not even mentioned in Bill) and the BORDER WALL, which is desperately needed for our National Defense, is not fully funded," Trump tweeted.
