Last night, as promised, former CNN anchor Lou Dobbs appeared on MSNBC’s “The Last Word with Lawrence O’Donnell” to debate Isabel Macdonald, the reporter for The Nation who wrote the story accusing Dobbs of hiring undocumented workers, even as he railed against the practice on his CNN and radio programs.

Update: Dobbs also appeared this morning on ABC’s “Good Morning America.” Video of that appearance is after the jump.
