Anthony Scaramucci keeps spilling White House tea in the 'Big Brother' house, and he says there's no way President Trump is going to be able to deliver on one of his biggest campaign promises ... draining the swamp.

Anthony, who worked in Trump's White House for 10 days before being fired, says the Prez won't be able to drain the swamp in D.C. ... and ya gotta hear his reason why.
