A federal judge ordered the White House on Tuesday to restore The Associated Press’ full access to cover presidential events, affirming on First Amendment grounds that the government cannot punish the news organization for the content of its speech.

U.S. District Judge Trevor N. McFadden, an appointee of President Donald Trump, ruled that the government can’t retaliate against the AP’s decision not to follow the president’s executive order to rename the Gulf of Mexico. The decision, while a preliminary injunction, handed the AP a major victory at a time the White House has been challenging the press on several levels.

“Under the First Amendment, if the Government opens its doors to some journalists—be it to the Oval Office, the East Room, or elsewhere—it cannot then shut those doors to other journalists because of their viewpoints,” McFadden wrote. “The Constitution requires no less.”

The AP’s decisions on what terminology to use are followed by journalists and other writers around the world through its influential stylebook. The outlet said it would continue to use Gulf of Mexico, as the body of water has been known for hundreds of years, while also noting Trump’s decision to rename it the Gulf of America. Different outlets have used different approaches, some skirting it by calling it the “Gulf.”

“For anyone who thinks The Associated Press’ lawsuit against President Trump’s White House is about the name of a body of water, think bigger,” Julie Pace, the AP’s executive editor, wrote in a Wall Street Journal op-ed. “It’s really about whether the government can control what you say.”
