MORE PROBLEMS FOR NIFONG in the Duke rape case:

The second dancer in the Duke rape case has said for the first time that the accuser told her to “go ahead, put marks on me” after the alleged attack.

Dancer Kim Roberts made the new allegation — which she has not shared with authorities — in an interview with Chris Cuomo that aired today on “Good Morning America.”

Roberts’ allegation comes after Durham District Attorney Mike Nifong’s admission in court last week that he has not yet interviewed the accuser “about the facts of that night.”

This case seems awfully weak.
