United Nations ambassador Susan Rice has withdrawn her name from consideration to be America's next Secretary of State.
In a letter to President Obama, the ambassador said any confirmation process would be "lengthy, disruptive, and costly."
The ambassador was considered a favorite to succeed Secretary Hillary Clinton.
Controversy overshadowed her candidacy, after she initially characterized the deadly attacks on a US consulate in Libya as a spontaneous response to an anti-muslim film.
"I didn't want to see a confirmation process that was very prolonged, very politicized, very distracting and very disruptive because there are so many things we need to get done as a country," said Rice.
"There is no doubt that Susan was qualified, there are other people who are qualified as well," said President Obama. "Her interest isn't in serving me but most importantly serving the country. She has done an outstanding job and I could not be more proud of her. She will continue to be one of the top member of my national security team."
Massachusetts Senator John Kerry is now considered the front-runner for Secretary of State post.
