President Obama will campaign with Rep. Joe Sestak (D-Pa.) later this month, the candidate the White House publicly opposed during the Democratic primary earlier this year.
Sestak, who's locked in a tough Senate race with former Rep. Pat Toomey (R-Pa.), will appear with the president in Philadelphia on Sept. 20.
The White House backed Sen. Arlen Specter (D-Pa.) in the Democratic primary. Obama campaigned and raised money for Specter in his race against Sestak.
Earlier this summer, Sestak hedged on whether he wanted a campaign visit from Obama ahead of November, telling reporters that he would welcome campaign help from first lady Michelle Obama.
