Bernie Sanders takes the opportunity to mock Donald Trump after he said Hillary Clinton's mid-debate trip to the bathroom was "disgusting."
"Donald Trump is very upset," Sanders said. "It is very hard for him to deal with, I don't know what his relationship with women has been in his life, but he has discovered that women go to the bathroom. And it has been very upsetting for him."
"I gotta be honest with you, lay it out on the table. I also went to the bathroom," Sanders continued, getting laughs from the crowd in Iowa early this morning.
