Both CBS Evening News anchor Katie Couric and MSNBC host Andrea Mitchell incorrectly asserted that President Obama is the only president in U.S. history who has had his citizenship doubted.I don't watch either one, so I don't know.
Then there is the question of who talked about the Birther issue most. This on-line article says it was MSNBC and CNN. But, they cheated and pulled the Data from the Pew Trust.
