Jimmy Kimmel took it upon himself to give President Donald Trump a proper roast in a new monologue before the upcoming White House Correspondents' Association dinner. Kimmel, 58, pointed out during the Thursday, April 23, episode of Jimmy Kimmel Live! that this year's White House Correspondents' Association dinner is breaking tradition by not having a comedian as its host. Instead, the WHCA chose mentalist and author Oz Pearlman to headline as the entertainer.
