The White House revoked Acosta’s Secret Service “hard pass” in a decades-long breach of protocol last Wednesday night, preventing the journalist from accessing press-friendly spaces on White House grounds. Pointing to the First and Fifth Amendment of the U.S. Constitution, the lawsuit alleges that both Acosta and CNN’s rights were violated by the suspension of these privileges.

In a statement released Tuesday morning, CNN announced that it filed its lawsuit in a DC District Court against six people, including the president, Press Secretary Sarah Sanders, Chief of Staff John Kelly, Kelly’s deputy William Shine, the U.S. Secret Service and its director Randolph Alles, as well as “John Doe,” the currently-unidentified agent who denied Acosta access to the grounds. The defendants are named because of their roles in enforcing and announcing Acosta’s suspension.

The lawsuit “demands the return of the White House credentials of CNN’s Chief White House correspondent,” according to the statement. “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.”

CNN’s legal actions are the latest step in an escalating battle between President Trump and the media. Trump has shown particular antipathy to CNN, regularly deriding its reporters and the network as a whole. In light of the president going as far as to call the press “the enemy of the American people,” it is fitting for there to be a lawsuit on the books titled “CNN vs. President Trump.”

The White House responded to CNN’s complaint in a statement by press secretary Sarah Sanders, accusing CNN of “grandstanding” by suing, and saying the administration “will vigorously defend against this lawsuit.” Sanders previously alleged (in a tweet that is still live) that Acosta placed his hands on a female White House intern during a heated exchange with Trump last Wednesday.

“Mr. Acosta is no more or less special than any other media outlet or reporter with respect to the First Amendment,” said Sanders. “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.”

Trump’s warlike stance against journalists, and his specific action to ban Acosta, flies in the face of decades of tradition and precedent. White House administrations on both sides of the aisle have sought to be accommodating of the press, erring on the side of inclusion, even for non-mainstream outlets. The well-known First Amendment attorney Floyd Abrams thinks CNN has a strong case in the precedent set by the 1977 ruling in favor of Robert Sherrill, a conservative journalist who was also denied access to the White House.

Furthermore, federal guidelines require that “officials of the Secret Service will be guided solely by the principle of whether the applicant presents a potential source of physical danger to the President and/or the family of the President so serious as to justify his or her exclusion from White House press privileges.” The administration has made no claims that Acosta presents a physical danger to Trump during his press briefings.

Abrams points out that those denied press privileges, “have to have notice… a chance to respond, and… a written opinion by the White House as to what it’s doing and why, so the courts can examine it.” He adds that, “We’ve had none of those things [in Trump’s banning of Acosta],” giving weight to CNN’s claim of due process violation.

As noted in CNN’s statement, “While the suit is specific to CNN and Acosta, this could have happened to anyone. If left unchallenged, the actions of the White House would create a dangerous chilling effect for any journalist who covers our elected officials.”

CNN Worldwide president Jeff Zucker emphasized the importance of taking action in an internal memo. “This is not a step we have taken lightly. But the White House action is unprecedented,” Zucker said.
