Glenn Beck responded to Van Jones' debate challenge by calling Jones an "unrepentant Communist revolutionary" and refusing to debate him.
Jones, who was driven out of the White House by Beck's campaign against him, challenged Beck to a debate on Saturday at the Netroots Nation conference.
On his Monday radio show, Beck repeated his charges against Jones, and said he had never made any untruthful claims about him.
"He is an unrepentant Communist revolutionary," Beck said. "He is a guy who stands with cop-killers. Period."
He also declined to debate Jones--for now.
"There's really not anything to talk about until you're honest and you say you want the overthrow of the government as you have in the past. The violent overthrow for a Marxist government. When you're honest, then people can have a debate."
