Eminem has dissed his share of pop stars and rappers, but on Tuesday night at the BET Hip-Hop Awards, he set his eyes on his biggest opponent yet: President Donald Trump.

Most people have been upset with Trump’s racist, xenophobic rhetoric and his discriminatory policies, and Eminem used his segment at the BET Hip-Hop Awards to call Trump out. In a video recorded in his stomping grounds of Detroit, Em called out Trump for his bigotry, his vendetta against black NFL players who kneel for the anthem, and more. He also advocated for Hurricane Maria victims in Puerto Rico and raised a fist for Colin Kaepernick.

And just to eliminate all confusion, Eminem drew a line in the sand with any of his fans who rock with Trump: if you support Trump, you don’t support Em.
