Best pals Matt Damon and Ben Affleck will co-host a fundraising event to help Newark Mayor Cory Booker in his run for a seat in the U.S. Senate. The Good Will Hunting stars will oversee the event at tycoon Ron Burkle's home, alongside fellow co-hosts JJ Abrams and Jennifer Garner. Tickets for the bash range from $1,000 (£666) to $10,000 (£6,666), and will help fund Booker's campaign to take over the seat left vacant by Senator Frank Lautenberg following his death in June (13). He will go up against Republican Steve Lonegan at the election on 16 October (13). Eva Longoria has already thrown her support behind Booker, joining him on the campaign trail in New Jersey earlier this month (Aug13) to urge locals to vote.
