By MICHELLE L. PRICE MILWAUKEE (AP) — The Republican National Convention starts Monday in Milwaukee, two days after Donald Trump was injured in an assassination attempt, with the violent scene at his campaign rally horrifying the country and amplifying already intense political divisions. Trump and his advisers are pledging resilience in the face of the attack, with plans going forward for the event to showcase the former president and his platform as his party formally chooses him to be its nominee. It was not immediately clear if and how Saturday’s attack would alter the four-day event, which normally has a celebratory atmosphere.
