London:
US vice president Joe Biden's daughter has been allegedly shown on a video snorting cocaine at a house party.
The video purports to show Ashley Biden, 27, snorting lines of white powder at a party in her home state of Delaware, the Times Online reported.
The White House was rocked yesterday by the claims, which surfaced days after Hillary Clinton, the US Secretary of State, declared that the United States shared the blame for Mexico's violent drug wars.
The New York Post said that it had viewed about 90 seconds of a 43-minute video being offered for sale by an anonymous male acquaintance of Ms Biden, through a Washington lawyer.
The video showed a woman resembling the Vice-President's daughter taking a red straw from her mouth, bending over a desk, inserting the straw into her nostril and snorting lines of white powder.
The woman then stands up and starts talking with other people in the room as a young man - identified as her boyfriend - watches from behind.
Radaronline.com, an online gossip site, said that one of its freelance reporters had also viewed the video.
The NY Post said that the seller originally wanted to sell the video to the media for $2 million, before reducing it to $400,000. Radaronline.com put the asking price at $250,000. The video was supposedly taken this year.
