3 military branches without Senate-confirmed leaders for first time in history, Defense Secretary says

The Navy on Monday joined the Army and Marine Corps in operating without Senate-confirmed military leaders because of Alabama Republican Sen. Tommy Tuberville's hold on top military nominations. 

Chief of Naval Operations Adm. Michael Gilday in a ceremony Monday morning relinquished his office as required by statute, and Adm. Lisa Franchetti took over in an acting capacity. 

It's the first time in the history of the Defense Department that three military services are without Senate-confirmed leaders, according to Defense Secretary Lloyd Austin.
