Trump Maher

Donald Trump totally lost it Sunday night, going on a hilarious diatribe over Bill Maher, claiming he agreed to have a second dinner with the "Real Time" host because he believed Bill was a "major pothead" and "He's got to stop, it's very bad for his health."

It's the longest post-Trump -- or Natalie -- has ever written ... more than 1300 words. It meanders from anger toward B.M. -- "COMPLETE AND TOTAL LOSER" -- to "The Apprentice" and how he says it was the greatest, most successful show in its day.

Trump goes after Bill again, but not before quoting CNN's Harry Enten, whom he says was "The Most Influential President of the Last Century."
