Charles Krauthammer reacted to the firing of FBI Director James Comey, saying that the Trump administration's stated reasoning for his termination is implausible.

"According to the letter by the deputy attorney general [Rod Rosenstein], this is about something that occurred on July 5," Krauthammer said.

Rosenstein's letter referenced Comey's recommendation against Hillary Clinton's prosecution for her email scandal, despite Comey laying out a case for such.

"So we start out with something that is highly implausible," Krauthammer said, adding that if that were the sticking point, Comey should have been fired during the presidential transition period last winter.

Krauthammer said that if their reasoning is true, it would be "inexplicable" to fire Comey for something that happened a year ago.

He added that it would be odd for Trump to fire Comey over something that many believe helped Clinton lose her bid for the White House.

Catherine Herridge reported that the firing may lead to another possible controversy. One of the top names for an interim director while a new one is being confirmed is Comey's lieutenant, Andrew McCabe.

McCabe came under fire last year after it was found his wife received $700,000 for a failed Congressional bid from several top Virginia Democrats, including Clinton ally Gov. Terence McAuliffe (D).
