PHOENIX (Reuters) - Sensing a potential turning point, Republican presidential nominee Donald Trump mounted a furious effort on Saturday to portray Democrat Hillary Clinton as unfit to lead the country after the latest chapter in her email controversy unfolded as he tries to mount a comeback.

With the Nov. 8 election only 10 days away, Trump devoted much of his stump speech to try to take the maximum advantage of the FBI's disclosure that it is investigating more emails as part of a probe into Clinton's use of a private email server.
