Want to attend President Obama’s birthday bash in Chicago? It’ll cost you $30,000.

Obama will be in his adopted hometown on August 5, headlining a fundraiser for Democratic U.S. Senate candidate Alexi Giannoulias, who has been trailing his opponent, Republican Mark Kirk, in campaign contributions.

While the president is in town, however, the Democratic National Committee will be doing some fundraising of their own.

Chicago Sun-Times columnist Michael Sneed reports that real estate mogul Neil Bluhm is hosting a private birthday party in his home for Obama, who turns 49 on August 4.
