 One week after the assassination attempt, former President Trump is back on the campaign trail in Michigan today. And for the first time since accepting the GOP nomination, he and running mate J.D. Vance hold their first rally. ABC's Jay O'Brien is in Grand Rapids. Trump is fresh off the RNC just days ago, where he delivered that message of unity in the wake of that assassination attempt. But his remarks there quickly veered back to old Trump campaign themes, like lashing out at his enemies, like airing grievances.
