Donald Trump -- Boycott Kanye!

Donald Trump himself is calling for a boycott of Kanye West, calling his antics last night "disgusting."

Trump tells TMZ he wants to boycott all things Kanye "so this kind of thing doesn't happen again."

Trump also thinks Kanye's hijack to honor Beyonce was B.S. -- "He couldn't care less about Beyonce. It was grandstanding to get attention."
