US President Barack Obama has paid tribute to what he called the "extraordinary role" Hillary Clinton played as Secretary of State.
In a joint interview on CBS, Mr Obama praised Mrs Clinton's "discipline, her stamina, her thoughtfulness, her ability to project".
Both Mr Obama and Mrs Clinton sidestepped questions about whether she might run for the presidency in 2016.
