 Trump made his first public appearance since being injured during a rally in Pennsylvania Saturday when he entered the Republican National Convention Monday evening. He did not deliver any formal remarks, but earlier in the day, Trump did announce his vice presidential pick, Ohio Senator J.D. Vance. North Dakota Governor Doug Burgum may serve in Donald Trump's cabinet if he wins a second term in the White House. Burgum told CNN Trump referred to him as Mr. Secretary during a call in which Trump told Burgum he would not be his running mate.
