Louis CK is hosting a fundraiser for his bud Bill de Blasio mayoral reelection campaign. The event, dubbed "Mayor Bill de Blasio's Birthday Party w/ Louis CK," goes down on May 12 at Brooklyn Bowl. Invites came via an email to folks who have previously supported the Mayor's campaign, and it's a minimum donation of $100 to attend.

These two have a history together, as Louis has attended fundraisers before, and Mayor De Blasio had a guest spot on Louie's fantastic new show Horace and Pete. You can watch that clip below.
