Hillary Clinton backs gay marriage

Former US Secretary of State Hillary Clinton has announced her support for gay marriage.

Gay and lesbian couples should enjoy equal rights that "includes marriage", Mrs Clinton said, in a five-minute video for a gay rights advocacy group.
Mrs Clinton added that she supports same-sex marriage "personally and as a matter of policy and law".
Other Democrats seen as possible 2016 presidential contenders have also publicly backed gay unions.
Vice-President Joe Biden, New York Governor Andrew Cuomo, and Maryland Governor Martin O'Malley - seen as possible presidential hopefuls - have also backed same-sex marriage.
