“We have more things to worry about than Bill Clinton’s sexual life,” Sanders said Sunday on ABC’s “This Week.”
Sanders also stood by his previous statement that Trump is a "pathological liar."
“I do not get engaged in personal attacks but Trump is over the edge,” he said. "The guy just comes up with things off the top of his head that are lies and someone has to say that.”
Although the Vermont senator defended Clinton against attacks from Trump, he remained confident he can beat his wife in Iowa despite trailing her in the polls.
“The turnouts we are seeing in big towns and small towns are extraordinary,” he said. “I think people are tired of establishment politics and establishment economics.”
