Democratic presidential candidate Joe Biden faces mounting calls to respond to a sexual assault allegation against him by a former employee.
Tara Reade, who worked for the former US vice-president nearly 30 years ago, says he sexually assaulted her in the halls of Congress.
Mr Biden has been accused of being “touchy feely” by multiple women, but this is the first public accusation of serious sexual misconduct against him.
The White House hopeful’s camp has denied it, but acquaintances of Ms Reade have confirmed she confided in them about her alleged ordeal.
With the claim looming during a presidential election year – the first such vote since the emergence of the #MeToo movement – let’s take a look at what exactly Mr Biden is accused of and how he has responded.
