(NBC News Channel) -- CNN is suing The White House, claiming that banning reporter Jim Acosta violates The Constitution.
The Secret Service took away Acosta's White House pass last Wednesday after a heated exchange during a news conference.
When Acosta asked President Donald Trump questions, the President told him "enough" and told him to give up the microphone.
When Acosta refused to hand over the microphone, a White House staffer tried to grab it from him.
The White House says that's why it took away Acosta's pass.
CNN filed a lawsuit in District Court Tuesday, claiming banning Acosta violates the Constitutional rights to freedom of the press and due process.
Press Secretary Sarah Sanders said in a statement: "We have been advised that CNN has filed a complaint challenging the suspension of Jim Acosta's hard pass. This is just more grandstanding from CNN, and we will vigorously defend against this lawsuit. CNN, who has nearly 50 additional hard pass holders, and Mr. Acosta is no more or less special than any other media outlet or reporter with respect to the First Amendment. After Mr. Acosta asked the President two questions each of which the President answered he physically refused to surrender a White House microphone to an intern, so that other reporters might ask their questions. This was not the first time this reporter has inappropriately refused to yield to other reporters. The White House cannot run an orderly and fair press conference when a reporter acts this way, which is neither appropriate nor professional. The First Amendment is not served when a single reporter, of more than 150 present, attempts to monopolize the floor. If there is no check on this type of behavior it impedes the ability of the President, the White House staff, and members of the media to conduct business."
