Washington (CNN) Former White House communications director Anthony Scaramucci said Wednesday that President Donald Trump "is a liar" and that he "should probably dial down the lying."

Appearing on "New Day" to promote his new book, "Trump: The Blue-Collar President," Scaramucci was asked by CNN's John Berman about the President's pattern of spreading falsehoods and what he would call someone who spreads lies.

Scaramucci said such people are "like a rascal, like a scoundrel."

"I asked you what do you call someone who likes to lie? You said a scoundrel," Berman replied. "Another thing you could call someone who likes to lie is a liar. Is he a liar?"

"OK, well we both know that he's telling lies. So if you want me to say he's a liar, I'm happy to say he's a liar," Scaramucci said.
