Penny Pritzker, the chief fundraiser for President-elect Obama's campaign, won't serve as Commerce Secretary, contrary to prior reports, according to a senior Obama official who spoke to The Swamp.

"Penny Pritzker ultimately has decided she does not want to do the Commerce thing," the source said.

CNN had reported that Pritzker was the top choice for the post and that Arizona Gov. Janet Napolitano (D) was the top choice to head the Homeland Security Department.

The Obama official, however, said that Napolitano's appointment isn't a done deal.

"I expect Napolitano will end up in the cabinet," the official told The Swamp. "But whether she ends up where the speculation is (has her), I don't know."
