POOL REPORT FROM ABC

Hillary proteststors (sic) are in front of the msnbc set. Chris Matthews walked on to the set, Hillary supporters started chanting "sexist pig, sexist pig", and booing him. Before he arrived the Clinton and Obama supporters were yelling at each other. There [are] about 200 people in front of the msnbc set. The group that was yelling back and forth at each other was fairly small - approx 15 ppl.
