WATCH: CNN's Anderson Cooper unloads on Sarah Sanders for brushing over Trump's unprecedented behavior

CNN's Anderson Cooper opened his Monday night show with an epic takedown of White House press secretary Sarah Huckabee Sanders.

Sanders tried to brush off the claims made in The New York Time anonymous op-ed and veteran journalist Bob Woodward's book as an event blown up by the media.

"Of course Sarah Sanders would try to turn this op-ed into media criticism by saying that it's sad and pathetic," Cooper said. "But It's not every day or every year or every administration, for that matter, that someone in the administration publishes a scathing criticism of the president words the op-ed user writes, 'impetuous, adversarial, petty, and ineffective.'"

Cooper added, "It's not every day that someone in the administration claims that many officials in that administration are working to frustrate parts of the president's agenda and his worst inclinations.

"It's not every day that someone writes, and I'm quoting, 'we believe our first duty is to this country, and the president continues to act in a manner that is detrimental to the health of our republic,'" he said.

He continued: "It's not every day that an administration official writes, the root of the problem is the president's amorality."
