Obama nominates Irish woman Samantha Power for top UN job
US President Barack Obama has nominated Irish-born Samanatha Power as the new US Ambassador to the UN.
Power was born in Dublin in 1970 but her family relocated to the US when she was nine in 1979.
She went on to study at Yale and won a Pulitzer Prize for her book on genocide in 2003, entitled 'A Problem From Hell, America and the Age of Genocide.'
She will leave her current role as head of the human rights division at the National Security Council.
Power was a senior foreign policy advisor to Barack Obama, and is considered to have played an instrumental role in shaping his foreign policy.
However, she was forced to resign during his first campaign after she made disparaging remarks about Hilary Clinton.
She returned to work for Obama soon after he took office and has been widely praised for her work, especially on the issue of the Libya intervention.
