Fox News:

Black Barack Obama delegate apparently called a black Hillary Clinton supporter an “Uncle Tom.”

Delmarie Cobb of Chicago, a Clinton delegate, told FOX News that Illinois Senate President Emil Jones, an Obama delegate, called her an “Uncle Tom” for speaking out in support of Clinton.

Apparently, Cobb accused Jones of gloating over Obama’s victory. Jones then insinuated that Clintons played “gutter politics,” according to Cobb, who ended the conversation by announcing it was “time for me to go.”

“I walked away and said good night and walked over across the hall to the elevators,” she recalled. “And he shouted across the lobby, ‘Uncle Tom!’ “And I came back over and said, ‘Excuse me, what did you just say?’ And he grabbed me by my arms and started laughing. And I said, ‘No, no. What did you just say?’ And he didn’t repeat it. And I said, ‘Did you call me an Uncle Tom?’ And then I came back with a barrage of things that I won’t repeat publicly.”

Later:

“She was spouting things about Barack,” Jones said. “What I said was, ‘Come on board, he’s a nice, clean cut guy and everything.’ I said, ‘We’ve got to stop all this. We’ve got too many doubting Thomases and we’ve got to get together.’ “And she was walking away and therefore she heard the last part of the word; she didn’t hear the whole part,” Jones added. “I cannot apologize for one misinterpreting what I said.”

The Chicago Sun-Times quoted several aldermen who witnessed the exchange and confirmed that Jones called Cobb an “Uncle Tom.”

Although Democrats at the convention are trying to project an image of unity, there is lingering bitterness between the Clinton and Obama camps, in part because each side accused the other of playing the race card during the primaries.
