George Clooney has thrown his support behind Democratic front runner Hillary Clinton, doing so in a letter to her supporters on Monday.

The letter serves as an invitation to Clinton supporters to enter a lottery for a chance to visit his home, where a fundraiser for the presidential hopeful will be held. In addition to lauding Hillary Clinton in his letter, George Clooney took some serious jabs at Donald Trump.

“If you listen to the loudest voices out there today, you’d think we’re a country that hates Mexicans, hates Muslims, and thinks that committing war crimes is the best way to make America great again,” Clooney wrote, according to CNN.

“In all of this clutter, there’s been one consistent voice. A voice of tolerance and experience, from a candidate who’s spent a lifetime fighting for the rights of the less fortunate. A candidate who knows firsthand the complexity of our international relationships,” George Clooney said of Hillary Clinton.

He went on to call Clinton, “the only grown-up in the room. And if ever there was a time for a grown-up, that time is now.”

George Clooney is hosting the upcoming Hillary Clinton fundraiser with his wife, Amal Clooney.
