From NBC's Mark Murray
At 7:45 am ET, about 150 demonstrators -- all of them Clinton supporters -- had assembled outside the hotel where the DNC Rules and Bylaws Committee meeting will take place today.
The protestors were holding pro-Clinton signs, wearing pro-Clinton T-shirts, and chanting "Count all votes! Count all votes!"
As we were walking into the hotel, the crowd erupted in applause as a car pulled up into the hotel's driveway. Who was in the car? Florida Sen. Bill Nelson, a Clinton supporter.
It's going to be an interesting day.
*** UPDATE *** By 8:30 am ET, the crowd has grown by a hundred or two. It's a sizeable crowd, but not huge. We also spotted a couple of Obama supporters in the audience. One was holding a sign reading, "Change the rules until I win."
