Alec Baldwin took aim at President Trump on Tuesday.

Actor Alec Baldwin took aim at President Trump on Tuesday.  "The United States has a National Socialist tumor in its body and it is growing day by day," Baldwin tweeted. "This alone should compel you to do everything in your power to get rid of Trump."  According to The Hill, the 'National Socialist" part appears to be a reference to Hitler's Nazi party, the full name of which was the National Socialist German Workers' Party. 
Baldwin and Trump have frequently traded barbs, particularly over his portrayal of Trump on "Saturday Night Live."
"Alec Baldwin, whose dying mediocre career was saved by his terrible impersonation of me on SNL, now says playing me was agony. Alec, it was agony for those who were forced to watch. Bring back Darrell Hammond, funnier and a far greater talent!" Trump wrote in a tweet months ago.
