Meanwhile, friction is increasing between Trump and top Republican leaders. On Monday, in an interview with The Washington Post, Trump refused to endorse the re-election campaigns of Arizona Senator John McCain and Wisconsin Congressmember Paul Ryan. Trump praised Ryan’s opponent in the race, saying he was “running a very good campaign.” Ryan’s opponent, Paul Nehlen, has defended Trump’s remarks about the Khans, while both Ryan and McCain publicly distanced themselves from Trump over his comments.
