 This is CBS News on the Hour, sponsored by O'Reilly Auto Parts. I'm Jennifer Kuiper. The president has hosted a 4th of July barbecue at the White House for military members and their families. CBS' Stacey Lynn reports. President Biden spoke for just a few minutes, thanking them for their service. At the end, he went to shake some hands and take some pics with the military members and their families when someone yelled out, keep up the fight, we need you. The president responded, I'm not going anywhere.
