George Clooney made his political proclivities known in an open letter that pointedly bashed Republican front-runner Donald Trump. The Hillary Clinton campaign emailed Clooney's letter to supporters on Monday, in which he called for voters to rally behind the Democratic presidential hopeful and her "voice of tolerance and experience." The actor-activist and his wife, Amal, a human-rights lawyer, are hosting a fundraiser for Clinton at their Los Angeles home next month.
