Rep. Harriet Hageman (R-Wyo.) made a wild geographical blunder at a House rules committee meeting on Monday when she suggested that San Diego borders the Gulf of Mexico.

Hageman went to bat for a bill — introduced by Rep. Marjorie Taylor Greene (R-Ga.) — that looks to require federal laws, maps and other materials to rename the body of water to the Gulf of America.

“I think another reason why we should change this to the Gulf of Amexi — of America versus the Gulf of Mexico is for over 40 years, the country of Mexico has been dumping raw sewage into the area near San Diego, California,” Hageman declared.

She went on to claim that both she and Environmental Protection Agency Administrator Lee Zeldin were recently in the area, adding that it’s a “horrific” situation and “environmental catastrophe” that Mexico refuses to fix.

“That is another reason why we need to retake and claim ownership of this area and make sure people do know that it is the Gulf of America,” she added.

Firstly, San Diego isn’t remotely close to the Gulf and is well over 1,200 miles away from the body of water.

And while Zeldin visited San Diego last month, he was in town to examine a sewage crisis in the Tijuana River, which flows from Mexico to Southern California before emptying in the Pacific Ocean.

The bill — which the GOP-majority committee advanced to the House floor — looks to codify an executive order signed by President Donald Trump, who in January called on Interior Secretary Doug Burgum to take “all appropriate actions” in renaming the body of water for governmental use.

Critics on X, formerly Twitter, swiftly clowned Hageman over her gaffe.
