A battered Trump is tested on multiple fronts

Donald Trump grappled Thursday with fallout from multiple recent missteps, amid a new round of unfavorable polls and as House Speaker Paul Ryan reiterates that his support for the Republican presidential nominee is not guaranteed. The brash billionaire's ability to stay on message during an intensifying general election campaign has been called into question by members of his own party, with Ryan delivering a pointed critique of Trump's performance 96 days before Americans choose between Trump and Democrat Hillary Clinton. The Republican flagbearer steered his campaign into the rough in recent days by provoking a clash with the family of a Muslim American soldier killed in action, and then declining to endorse Ryan and Senator John McCain, the party's 2008 nominee, in their congressional re-election campaigns.
