President Obama's political operation took a shot at Sarah Palin today, accusing her of lying on her media blitz.

"It's dangerous," Organizing for America Director Mitch Stewart said of Palin's book tour.

He continued:

"Remember, this is the person who coined the term 'Death Panels' -- and opened the flood gates for months of false attacks by special interests and partisan extremists.

"Whatever lie comes next will be widely covered by the media, then constantly echoed by right-wing attack groups and others who are trying to defeat reform."

Stewart asks supporters to help raise $500,000 to "push back against Sarah Palin and her allies."
