President Donald Trump plans to attend an unusual gathering of U.S. generals and admirals at a military base in Virginia on Tuesday.

It was not immediately clear whether Trump planned to give a formal address to the hundreds of military leaders from around the world at the base at Quantico, Virginia, or whether his remarks would be made public.

Defense Secretary Pete Hegseth, who summoned the generals and admirals, is expected to speak about grooming and fitness requirements, and other aspects of what he calls a shift toward a “warrior ethos” at the Pentagon.
