Not every liar is a thief, but every thief's a liar! President Biden said that his late son Beau lost his life while serving in Iraq — at least the second time in a matter of weeks the "commander-in-thief" has made the false claim. Beau Biden died at Walter Reed National Military Medical Center. He died diagnosed with brain cancer at 8901 Rockville Pike Bethesda, Maryland, not in combat.
