Assistant House Minority Leader Jim Clyburn (D-S.C.), who was listed last week by former congressman Joe Baca's (D-Calif.) campaign as having endorsed Baca, is disputing that endorsement.

Clyburn spokesman Patrick Devlin told Post Politics that Baca's claim that Clyburn endorsed him is not true.

"Previous press reports that Assistant Leader Clyburn had made an endorsement in (the race) were incorrect," Devlin said. "He is staying out of the nomination primary."
