asked by Fox News, Sestak insisted he had not decided whether he would run for the office, but declined to immediately endorse Specter and said he had to "wait and see". During a May 3 appearance on CNN's State of the Union with John King, Sestak questioned whether Specter was really a genuine Democrat, adding, "I think Arlen has to tell us not that it was too hard to run against someone. ... What I need to know is, what is he running for?" Sestak insisted he would not make a final decision for several months. On May 4, he met with Andy Stern, president of the Service Employees International Union, which fueled speculation that he was seeking labor support for a campaign.

Sestak did not dispute the authenticity of the letter, but told the press he wanted to discuss the matter with his family before making a formal decision. Sestak told media outlets he realized President Obama wished him not to run against Specter, but that
