Well, he is an asshole.

Via LVRJ:

Hotel-casino developer Steve Wynn and actor George Clooney offered vastly different accounts Tuesday of a dinner that ended in verbal fireworks.

Wynn said Clooney “got drunk” from downing tequila shots and stormed off after delivering an F-bomb.

The two-time Oscar winner issued the following statement in an email sent through his publicist: “There were nine people at that table … so you can ask them. … Steve likes to go on rants.

“He called the president an asshole … that is a fact … I said the President was my longtime friend and then he said ‘your friend is an asshole.’ … At that point I told Steve that HE was an asshole and I wasn’t going to sit at his table while he was being such a jackass.

“And I walked out. There were obviously quite a few more adjectives and adverbs used by both of us. Those are all the facts. It had nothing to do with politics and everything to do with character.”

The incident occurred two weeks ago at Botero restaurant, inside Wynn’s Encore hotel.
