The lawsuit is a response to the White House’s suspension of Acosta’s press pass, known as a Secret Service “hard pass,” last week. The suit alleges that Acosta and CNN’s First and Fifth Amendment rights are being violated by the ban.

The suit was filed in U.S. District Court in Washington, D.C. on Tuesday morning.

Both CNN and Acosta are plaintiffs in the lawsuit. There are six defendants: Trump, chief of staff John Kelly, press secretary Sarah Sanders, deputy chief of staff for communications Bill Shine, the director of the Secret Service, and the Secret Service officer who took Acosta’s hard pass away last Wednesday. The officer is identified as John Doe in the suit, pending his identification.

The six defendants are all named because of their roles in enforcing and announcing Acosta’s suspension.

In a statement on Tuesday morning, CNN said it is seeking a preliminary injunction as soon as possible so that Acosta can return to the White House right away, and a ruling from the court preventing the White House from revoking Acosta’s pass in the future.

“CNN filed a lawsuit against the Trump Administration this morning in DC District Court,” the statement read. “It demands the return of the White House credentials of CNN’s Chief White House correspondent, Jim Acosta. The wrongful revocation of these credentials violates CNN and Acosta’s First Amendment rights of freedom of the press, and their Fifth Amendment rights to due process. We have asked this court for an immediate restraining order requiring the pass be returned to Jim, and will seek permanent relief as part of this process.”

The White House Correspondents’ Association said it “strongly supports CNN’s goal of seeing their correspondent regain a US Secret Service security credential that the White House should not have taken away in the first place.”

CNN also asserted that other news organizations could have been targeted by the Trump administration this way, and could be in the future.
