Late night comedy star Jimmy Kimmel fired back at Donald Trump Tuesday, hitting him with a zinger just horus after the president announced that funnyman and outspoken critic would be the latest to be fired.

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.”
