-who have made rape accusations against Bill Clinton, Trump escalated his attack on Hillary and Bill Clinton in an interview with WaPo in which Trump called the circumstances of Vincent Foster's death "very fishy."

"He had intimate knowledge of what was going on," Trump said of Foster's relationship with the Clintons. "He knew everything that was going on and then all of a sudden he committed suicide."

As a reminder, Vince Foster, a longtime friend of the Clintons, was deputy White House counsel in the first few months of Clinton's presidency.  He was found dead from a gunshot wound to the mouth in July 1993. The three official investigations into Foster's death concluded he committed suicide as he suffered from depression, however unproven theories have constantly swirled that the Clintons were involved in Foster's death.
