The moderators asked Obama about a recent statement of support from Nation of Islam leader Louis Farrakhan. Obama said he considers Israel's security "sacrosanct" and has denounced Farrakhan's anti-Semitic remarks.
Clinton responded that she had "rejected" unwelcome support in her 2000 Senate campaign at some political risk and said his denunciation was not enough. "I don't see a difference between denouncing and rejecting," Obama said, but "I'm happy to concede the point and I would reject and denounce."
Obama hedged about whether he would take public money for the general election if he is the nominee, as he once said he would. Clinton was vague on when she'd release her tax returns except to say not before the next primaries. "I'm a little busy right now," she said.
