A prominent Pennsylvania Democrat has sued Sen. Barack Obama, the Democratic National Committee and the Federal Election Commission, claiming that Obama is not a natural-born citizen and, therefore, is not eligible to be president of the United States.

Philip J. Berg, a former member of Pennsylvania's Democratic State Committee and former deputy attorney general of Pennsylvania, filed the lawsuit this week in U.S District Court, asking the court to declare Obama ineligible for the presidency and to prevent him from running for the position.

However, a WND investigation has found that at least part of Berg's lawsuit relies on discredited claims.

A separate motion was also filed seeking a temporary restraining order on Obama's presidential campaign until Obama's eligibility can be verified. ....

If any, much less all, of these allegations are true, the suit claims, Obama cannot constitutionally serve as president. ....

Berg claims his lawsuit is necessary, not only to protect the Constitution, but also to protect the integrity of the Democratic Party.

'If the DNC officers and/or leaders had performed one ounce of due diligence, we would not find ourselves in this emergency predicament, one week away from making a person the nominee who has lost their citizenship,' said Berg in his press release. 'The injunctive relief must be granted because failing to do so, (the DNC's) inaction defrauds everyone who voted in the Democratic Primary.'
