Washington: A one-time Democratic nominee for Nevada states Lieutenant Governor has accused former US Vice President Joe Biden of kissing and touching her without her consent during a November 2014 campaign event that made her feel "uneasy, gross, and confused".

In an essay published on Friday by The Cut, an arm of New York magazine, Lucy Flores wrote that when she learned that the then Vice President had offered to appear at a rally in Nevada to support her campaign she was grateful. But that feeling changed, she said, when Biden approached her from behind as she was getting ready to address the crowd.
