Washington D.C.: Republican presidential nominee Donald Trump closed out a rough week for his campaign on Saturday by escalating personal attacks on Democrat Hillary Clinton, questioning her stamina and saying she should be in prison for her handling of classified emails.
After a week in which he drew wide criticism for a public feud with a former beauty queen, Trump sought to rebound with a highly negative attack on his opponent in the Nov. 8 election, with a second presidential debate against her looming in a week.
