 Former President Trump got a hero's welcome on day one of the Republican National Convention in Milwaukee. Mr. Trump is now the GOP's 2024 standard-bearer, and he's chosen Senator J.D. Vance of Ohio as his running mate. Teamster's President Sean O'Brien says it was an honor to be the first Teamster in the union's 121-year history to address the GOP National Convention. Yesterday, it was the economy. Today, security is the focus for the Republicans at their national convention.
