The Hollywood Reporter writes that Affleck and Damon, along with Jennifer Garner, producer J.J. Abrams and his wife Katie McGrath, former Disney CEO Michael Eisner, and a slew of other high-profile supporters, will co-host Booker at businessman Ron Burkle’s home on Sep. 23.

Tickets to the celeb-packed fundraiser will range in price from $1,000 to $10,000, according to the Reporter.

The revelation that Affleck, 41, would don the bat suit drew sharp criticism from many social media users last week. But Booker, a prolific Twitter user, came to the “Argo” director’s defense, tweeting that he was “pro-Ben.”
