Bill Clinton wasn't in the audience as Hillary Clinton fought through the first Democratic debate, but he was supporting her — from a Las Vegas hotel room. (The debate is taking place in Las Vegas but no word about why he wasn't present.) Check out his tweet encouraging her bid for POTUS.

What happens in Vegas...is I watch @HillaryClinton [1] prove she's the most qualified candidate for POTUS. #ImWithHer [2] pic.twitter.com/ax1d56Whwt [3]
