A prominent Philadelphia attorney and Hillary Clinton supporter filed suit this afternoon in the U.S. District Court for the Eastern District of Pennsylvania against Illinois Sen. Barack Obama, the Democratic National Committee and the Federal Election Commission.

He seeks to ban Obama from being allowed to run for president and to be selected as the Democratic candidate for 2008 election.

Philip Berg, the filing attorney, is a former gubernatorial and senatorial candidate, former chair of the Democratic Party in Montgomery (PA) County - cited a number of unanswered questions regarding the Illinois senator's background, and in today's lawsuit maintained that Sen. Obama is not a natural born U.S. citizen or that, if he ever was, he lost his citizenship when he was adopted in Indonesia.
