George W. Bush Has a Surprising Term for Hillary Clinton

We all know that George W. Bush calls Bill Clinton his "brother from another mother." So what does that make Hillary Clinton? Bush revealed his surprising term for the former first lady on Thursday.

"My sister-in-law."

Bush made the comment to CNN's Candy Crowley, who then asked Bush if his brother, Jeb, could run against his sister-in-law in a race for president.

"Yeah, and I think he'd beat her," he said with a slight chuckle.
