Susan Rice ends bid to succeed Hillary Clinton
UN Ambassador Susan Rice has withdrawn her name for consideration to succeed Hillary Clinton as US secretary of state, the White House says.
In a letter to the president, Ms Rice said her confirmation process would be "disruptive and costly", NBC News said.
Ms Rice has been at the centre of Republican criticism over the Obama administration response to a deadly attack on a US consulate in Libya.
