Sen. Tommy Tuberville (R-Ala.) on Capitol Hill on Nov. 28. (Elizabeth Frantz for The Washington Post)

Regarding the Sept. 5 op-ed by Navy Secretary Carlos Del Toro, Air Force Secretary Frank Kendall and Army Secretary Christine Wormuth, “Don’t leave national security on hold”:

Sen. Tommy Tuberville (R-Ala.) is blocking the Senate from confirming some 300 military promotions, leaving critical seats without a leader, including the top officer of the Marine Corps, Army and Navy. Mr. Tuberville is putting his political ambition and need for attention above the lives and livelihoods of service members.
