New York, March 30 : The lawyer representing US Vice President Joseph Biden's daughter's 'friend', who claimed having shot a video of her purportedly snorting cocaine, has abandoned the case.

Thomas Dunlap revealed he was no longer the attorney for the man who was trying to sell the 43-minute tape that allegedly showed Ashley Biden taking lines of white powder at a party in Deleware.

"I can't comment. I can't make any comment on anything about it," the New York Post quoted him as saying when questioned about what led to the split.

According to RadarOnline. com, Dunlap reportedly ditched his former client because "he did not want to be involved due to circumstances surrounding the publicity of the matter."

The video, around 90 seconds of which was shown to the New York Post, allegedly shows a woman similar to Ashley taking putting a pipe into her nostril and snorting lines of the banned substance.

She is later spotted chatting up with other people in the room, before reaching a point where she screams, "Shut the f--- up!"

While the dialogue is less clearly audible, the woman is then reportedly seen making repeated references to the drugs. (ANI)
