A group of Democratic lawmakers is pressing War Secretary Pete Hegseth for more information on his decision to remove several officers from consideration for promotion.

The Democratic senators urged Hegseth to clarify his “decision-making process and rationale for removing qualified Officers from promotion consideration” after the secretary made headlines for blocking several Navy officers’ promotions to one-star admirals in early June. Sens. Elissa Slotkin (D-MI), Jon Ossoff (D-GA), Richard Blumenthal (D-CT), Kirsten Gillibrand (D-NY), Dick Durbin (D-IL), Cory Booker (D-NJ, and Jeff Merkley (D-OR) penned the letter sent to Hegseth on Monday.
