Accusing the White House of a “targeted attack” on editorial independence that “strikes at the very core of the First Amendment,” The Associated Press on Friday filed a lawsuit against three Trump administration officials over its blocked access to all presidential events.

The administration announced earlier this month that AP reporters would not be permitted to cover press events at the White House, Mar-a-Lago, or on Air Force One due to its editorial decision to continue referring to the Gulf of Mexico by the name that has been internationally recognized for more than 400 years.

President Donald Trump issued an executive order in January stating that the Gulf of Mexico would be renamed the Gulf of America. Trump has the authority to change a body of water’s name for official government purposes, and some bodies of water are called by different names in different countries—for example, the Gulf of California is known as the Sea of Cortez in Mexico.

The APsaid it would acknowledge Trump’s chosen name for the body of water, but continue officially referring to it as the Gulf of Mexico.

“The press and all people in the United States have the right to choose their own words and not be retaliated against by the government.”

As Mexican President Claudia Sheinbaum said this month as she threatened to sue Google for changing the Gulf of Mexico’s names in its maps feature, the U.S. does not have sovereignty over the body of water, and Trump cannot unilaterally order other entities to call it by his chosen name.

The AP on Friday said in its lawsuit that “the press and all people in the United States have the right to choose their own words and not be retaliated against by the government.”

The suit names White House Chief of Staff Susan Wiles, Deputy Chief of Staff Taylor Budowich, and Press Secretary Karoline Leavitt, who has said in briefings that it is “a fact” that the body of water off the western coast of Florida and the southern coasts of several other states is called the Gulf of America.

The news outlet called on the U.S. District Court in Washington, D.C. to stop the White House from blocking its journalists from gathering news at presidential events.
