CNN's coverage of the Super Tuesday primaries got sidetracked for a few minutes when pro- and anti-Trump commentators lit into one another.  Van Jones and Jeffrey Lord had a tense tête-à-tête that looked for a moment as if it might erupt into a brawl.

Pop some popcorn and enjoy the show.

In both cases, Jeffrey Lord, who has been CNN’s chief Trump defender for months, stood up for the Republican frontrunner unequivocally. Recently, Lord has been comparing the KKK’s embrace of Trump to Rev. Jeremiah Wright’s relationship with Barack Obama and highlighting the Klan’s historic associations with Democrats. But in Jones’s words, Wright “never lynched anybody, never killed anybody” and “never put anybody on a post.”

“You guys play these word games and it is wrong to do in America!” Jones said, getting more and more heated. “I don't care how they voted 50 years ago,” he said of the KKK. “I care about who they killed.”

Lord ultimately resorted to the argument that Jones was the one “dividing people” with his rhetoric. “We're all americans here, Van,” he said. “This is what liberals do. You are dividing people by race.”

“The Klan divides by race, the Klan killed people by race,” Jones shot back.

As the two men continued to go back and forth, CNN’s camera remained locked on them. Anchor Anderson Cooper didn’t dare interrupt the fight. It took David Axelrod with a bit of comic relief—“Well, I think this is going well”—to break the tension and move things along.

Easily, this is the best moment from TV coverage of the primaries last night.
