Former US Secretary of State Hillary Clinton has testified she has no information regarding the criminal activities of the late convicted sex offender Jeffrey Epstein.

Ms Clinton has appeared before members of Congress in the the first of two days of hearings, which will also see former President Bill Clinton appear.  

It comes as journalists raise concerns that some documents have been withheld, some relating to a woman's allegations of abuse levelled at the current US President Donald Trump.
