“There are other Democrats who want Trump to have to give the State of the Union during a shutdown,” ​Mick ​Mulvaney​, the head of the Office of Management and Budget, told “Fox News Sunday.”

Mulvaney said some Democrats want to rain on Trump’s parade when he delivers the speech to a joint-session of Congress on Jan. 30.

“I really do believe that at heart here there was an interest by some folks in the Democratic Party to deny the president sort of the victory lap of the anniversary of his inauguration, the chance to talk about that success of the tax bill, success with the economy and jobs,” ​he said on Fox. “And I think if they get over that, there’s a chance this thing gets done before 9 a.m. on Monday.”
