The New York Times on Thursday filed a lawsuit challenging new restrictions on reporters who cover the Pentagon, which the newspaper says violate the U.S Constitution's free press protections.
The suit against the Defense Department and Secretary Pete Hegseth comes nearly two months after reporters from The Times and other mainstream news outlets, including CBS, CNN, Fox News, and NBC staged a dramatic walkout of the Pentagon and surrendered their credentials after refusing to comply with the rules.
Those outlets have been replaced by reporters who are broadly sympathetic to the Trump administration.
The Pentagon in October presented reporters who had desks there a 21-page rulebook that bars journalists from seeking or publishing information that has not been explicitly authorized by the Defense Department, even if the material is unclassified or obtained off Pentagon grounds.
Outlets that refused to abide by the rules lost their Pentagon credentials.
The Times' lawsuit, filed in U.S. District Court in Washington, D.C., asks a judge to block the Pentagon from enforcing the policy, and to declare it unconstitutional.
"The policy, in violation of the First Amendment, seeks to restrict journalists' ability to do what journalists have always done â ask questions of government employees and gather information to report stories that take the public beyond official pronouncements," the suit says.
The rules "deprive the public of vital information about the United States military and its leadership," the suit says.
The complaint also says that the Defense Department gave itself "unbridled discretion" to enforce the rules as it sees fit.
Chief Pentagon Spokesman Sean Parnell, who is named as a defendant in the suit, told CNBC that the Defense Department "is aware of the New York Times lawsuit and [looks] forward to addressing these arguments in court."
The Times did immediately return a request for comment.
The Pentagon's media rules were the latest step in Hegseth's broader push to reshape the press corps.
Since arriving at the department in January after a contentious confirmation fight, Hegseth has stripped several national outlets of in-house workspaces, tightened rules on where reporters can move inside the building, and reassigned offices to conservative outlets and pro-Trump media figures willing to sign the agreement.
Press-freedom advocates, including the Reporters Committee for Freedom of the Press, say the Pentagon policy goes beyond past fights over individual White House press badges. Rather than targeting one reporter at a time, they argue, the rules bind the entire press corps â giving the Pentagon broad authority to revoke access based on the stories they pursue.
"The Pentagon's press access policy is unlawful because it gives government officials unchecked power over who gets a credential and who doesn't, something the First Amendment prohibits," Reporters Committee for Freedom of the Press Vice President of Policy Gabe Rottman said in a statement Thursday, after the Times filed its suit.
