U.S. Sen. Tommy Tuberville, R-Ala., is among the co-sponsors of a Senate bill that would ban transgender people from serving in the U.S. military.

“The world is on the brink of a major conflict, and America’s military must be ready to fight at a moment’s notice,” Tuberville said in a statement from U.S. Sen. Marco Rubio., R-Fla., the main sponsor of the Ensuring Military Readiness Act.

The bill would prevent anyone with a history or diagnosis of gender dysphoria from serving in the military, with limited exceptions.

“Now is not the time to socially experiment with our armed forces at the expense of readiness, morale, and our national defense,” Tuberville continued. “The military maintains rigorous mental and physical requirements because our service members must be as capable and deployable as possible.”

The Alabama senator said those requirements should “include all conditions that make a service member physically unfit to serve, including the long and expensive process of gender transition.”

Rubio claimed President Biden has turned the military “into a woke social experiment.”

“It is a stupid way to go about protecting our nation,” the Florida senator said. “We need to spend more time thinking about how to counter threats like China, Russia, and North Korea and less time thinking about pronouns.”

The bill is also co-sponsored by Sens. Marsha Blackburn, R-Tenn.; Ted Budd, R-N.C.; and Mike Braun, R-Ind.
