Those are his words."Trump's told a rally in Charlotte, N.C., that he regrets some of his language during primary debates and other campaign events, especially if he &ldquo;caused personal pain.&rdquo;Trump, whose attacks have targeted Mexicans, women, a federal judge, parents of a slain U.S. soldier and fellow Republicans, among others, did not specify which comments he regretted.Conway said Trump's tone shows what he can bring to the White House.&ldquo;I certainly hope America heard him last night,&rdquo; Conway said. &ldquo;Because of all the people &hellip; who have been saying, &lsquo;Hey, let&rsquo;s get Trump to pivot, let&rsquo;s get him to be more presidential&rsquo; &mdash;&nbsp;that is presidential.&rdquo;Conway did not rule out the possibility that Trump could apologize to Khizr and Ghazala Khan, the Muslim parents of an Army captain who was killed in Iraq in 2004, for his harsh criticism of their appearance at the Democratic National Convention."He may," she said.
