After decades of the White House Correspondents Dinner (WHCD)—put on by the White House Correspondents Association—featuring a roast style comedian as the guest speaker, the WHCA announced Monday it would replace the usual comedian with author and presidential biographer, Ron Chernow. And both last year's speaker, comedian Michelle Wolf, and President Donald Trump had something to say about it on Twitter.

The annual event is a century old tradition. According to last year's dinner chair, the WHCD "has been and will continue to be a celebration of the First Amendment and the important role played by an independent news media in a healthy republic."
