       The Pentagon announced on Monday that Sgt. William Jerome Rivers, 46, of Carrollton, Georgia; Spc. Kennedy Ladon Sanders, 24, of Waycross, Georgia; and Spc. Breonna Alexsondria Moffett, 23, of Savannah, Georgia, were killed in a drone attack over the weekend on the U.S. base in Jordan near the border with Syria and Iraq.

       In a press briefing on Tuesday, National Security Council spokesperson John Kirby confirmed that Biden had spoken with families of the fallen.

       "He expressed to them how proud we all are of their service, how we mourn and feel sorrow over their loss, made sure that those families knew that, not only was that service and sacrifice, going to be honored and respected, but that they would continue to get the support that they need as they work through what no family wants to have to go through," he said.
