Senate Majority Leader Chuck Schumer called out Sen. Tommy Tuberville on Thursday, saying the Alabama senator’s defense of white nationalists was “utterly revolting.”

Schumer also criticized Tuberville’s holds on more than 180 military nominations over objections to new Defense Department policies expanding abortion access, arguing the move is endangering military readiness.

“Sen. Tuberville needs to do two things: he needs to come out and state clearly and unequivocally that white nationalism is un-American, and he needs to drop his destructive holds on hundreds of our senior military leaders,” the New York Democrat said on the Senate floor. “This farce is endangering our national security, putting the lives of men and women who have served our country for decades in real trouble, and it needs to end.”

In an interview with WBHM in Birmingham, Tuberville was asked if he believed white nationalists should be allowed to serve in the military.

“They call them that,” Alabama’s senior senator said. “I call them Americans.”

Schumer said the remark was “profane and dangerous.”

“Revolting. Utterly revolting. Does Senator Tuberville honestly believe that our military is stronger with white nationalists in its ranks?” the majority leader said.

“I cannot believe this needs to be said, but white nationalism has no place in our armed forces and no place in any corner of American society. Period. Full stop. End of story,” he continued. “I urge Senator Tuberville to think about the destructive spectacle he is creating in the Senate. His actions are dangerous. His words are gravely damaging. And his refusal to think about the consequences of his actions on our military personnel and families is a stain on this Chamber.”

Tuberville is holding up 184 Defense Department nominations over the agencies policies that allow service members to request administrative absence for “non-covered reproductive health services,” which includes elective abortions and IVF, for themselves or to accompany their partners. The policies also provide transportation allowances to travel to states where reproductive care is more expansive.

Alabama’s senior senator contends the policies are unlawful.

On Wednesday, Senate Minority Leader Mitch McConnell, R-Ky., said he does not support Tuberville’s stance.

“I don’t support putting a hold on military nominations, I don’t support that,” McConnell told reporters, according to The Hill.
