The Latest: RNC says Trump will bring message of unity

WASHINGTON (AP) — The Latest on the 2016 presidential campaign (all times local): 9:25 a.m. Reince Priebus, chairman of the Republican National Committee, says he expects Thursday night will be a turning point in Donald Trump's bid for the presidency. Priebus says that's when Trump will likely speak at the GOP convention, which starts Monday. Priebus tells ABC's "This Week" that Trump is already an intriguing figure to Americans. But Priebus says he believes Trump's speech on Thursday will give them a chance to see his presidential side and erase any doubt about Trump's ability to run the White House. Priebus called Trump's selection of Indiana Gov. Mike Pence as his running mate a "mature pick." He also said he doesn't expect GOP opponents of Trump will successfully disrupt proceedings this week at the GOP convention. ___ 5:00 a.m. Hillary Clinton's campaign is launching a major voter mobilization drive during the Republican National Convention. Campaign officials say the presumptive Democratic nominee is setting a national goal of persuading more than 3 million people to register and commit to vote in the 2016 election. Clinton intends to announce the plan on Monday in a speech to the NAACP convention in Cincinnati, followed by a stop at an Ohio voter registration event with volunteers. She is kicking off the voter drive as Republicans meet in Cleveland to nominate businessman Donald Trump at their national convention. The mobilization effort aims to capture the energy of Democrats watching the GOP convention from home each evening and harness it into a stronger voter base.
