COLORADO SPRINGS, Colorado (AP) - As Republican loyalists continue to flee, Donald Trump ignited new party tensions Tuesday by refusing to endorse House Speaker Paul Ryan or a pair of senators seeking re-election, a remarkable display of party division just three months before Election Day. The Republican presidential nominee told The Washington Post he's "just not quite there yet," when asked about an endorsement of Ryan, who faces a primary election next week. In doing so, he echoed the House speaker's comments of almost three months earlier, when the Wisconsin congressman was initially reluctant to embrace Trump as his party's standard bearer.
