 Donald Trump held his first public campaign rally since he was injured in an assassination attempt, an event in the battleground state of Michigan yesterday, alongside his new running mate. The joint rally with Ohio Senator J.D. Vance was the first for the pair since they became the GOP's nominees at the Republican National Convention this past week. After appearing uncharacteristically subdued and emotional during the convention, Mr. Trump was back in rally mode yesterday, peppering his address with jokes that sparked laughter from an enthusiastic crowd.
