“I don’t want to cause any controversies so I won’t say no names, but this motherf---er Donald Trump, I can’t stand,” a video shows the rapper telling the crowd on Saturday. “So before we get into this next song, 'Reading,' we would like to request something of you.”

The rapper then started the chant by telling the crowd, “When I say f---, you say Trump.” They appeared happy to assist. 

The chant was first reported by Entertainment Weekly.

It's not the first time Eminem has criticized Trump. He came out with a new rap before the November presidential election last year that referred to the then-GOP presidential nominee as a “loose cannon.”
