President Donald Trump kept up his blizzard of tweets on Sunday morning with a threat that he is "willing to shut down the government" if he doesn't get his wall.

With Trump spending Sunday morning lashing out at Democrats and the media -- calling the free press the "Enemy of the People" -- Trump once again attacked Congress for not giving him what he wants.

In particular, he wants his wall built and he is willing to bring the government to a standstill if he is not appeased.

"I would be willing to 'shut down' government if the Democrats do not give us the votes for Border Security, which includes the Wall! Must get rid of Lottery, Catch & Release etc. and finally go to system of Immigration based on MERIT! We need great people coming into our Country!" he tweeted.
