Jimmy Kimmel is exercising his First Amendment right as a U.S. citizen and firing back at Donald Trump after the President of the United States hinted his late-night talk show would be canceled next.

Kimmel, who has been engaged in a years-long feud with Trump, didn’t appear fazed by the president’s claim. “I’m hearing you're next,” he wrote on his Instagram Story. “Or maybe it’s just another wonderful secret.”

The response was a reference to a birthday message Trump allegedly wrote in 2003 to his then-friend Jeffrey Epstein, who would be convicted of sex crimes in 2008 and later died in a Manhattan jail cell while awaiting trial on federal sex trafficking charges.
