WASHINGTON – Joe Sestak will formally launch his Senate campaign Wednesday at Independence Hall, he announced in a news release Monday.

Sestak, a former admiral and Delaware County congressman, has long made clear that he intended to run for Senate in a bid to unseat Republican Pat Toomey in 2016. He has already been fundraising and making appearances across the state in the hopes of a rematch from their race in 2010.

Sestak "is running to restore Americans' lost trust in their political leaders by being accountable to the people," said the announcement.

He is so far the only Democrat to make serious moves towards a run, though there have been whispers of interest from others.

Philadelphia District Attorney Seth Williams has hinted at a run. Montgomery County Commissioner Josh Shapiro has explored the idea, and state Sen. Vincent Hughes, of Philadelphia, and former Congressman Chris Carney have also floated the possibility of seeking the Democratic nomination.
