Asked Thursday about whether the president's heated rhetoric on Twitter contributes to creating a violent atmosphere, White House Deputy Press Secretary Sarah Huckabee Sanders said the president has never suggested the use of violence. She defended his actions as self-defense.
"The president in no way form or fashion has ever promoted or encouraged violence. If anything, quite the contrary. And he was simply pushing back and defending himself," Sanders said Thursday.
CNN's Senior Media Correspondent Brian Stelter posted a statement from CNN on Sunday morning, which said the president's behavior is "far below the dignity of his office."
CNN statement responding to the president: "We will keep doing our jobs. He should start doing his."
