Disgraced ex-congressman Anthony Weiner, who is Jewish, has become a protagonist in the latest drama engulfing Democratic candidate Hillary Clinton.

Mrs Clinton's campaign was rocked on Friday after the FBI said that new emails relevant to the investigation into her private email server had been discovered on a computer belonging to Mr Weiner, the estranged husband of a top aide to the Democratic hopeful.

The FBI said the emails had surfaced during an investigation into illicit text messages sent by Mr Weiner to a 15-year-old girl in North Carolina.
