(CNN) – Rep. Joe Sestak said that President Obama called to congratulate him Tuesday night following his victory over Sen. Arlen Specter, the Republican-turned-Democrat who was backed by the president in this primary.
Obama "couldn't have been nicer," Sestak said in an interview Wednesday on CNN's American Morning. Watch Sestak on AM 
Sestak also said that president told him, "I'm there for you and I look forward to working with you and getting you in the United States Senate."
When Specter switched political parties last year, Obama and Vice President Biden publicly pledged their support for him in the primary. While the president appeared in radio and television ads for the veteran senator, Obama did not appear on the campaign trail with Specter in the closing days of race.
