Controversial U.N. ambassador to step down

WASHINGTON (AP) -- Unable to win Senate confirmation, U.N. Ambassador John Bolton will step down when his temporary appointment expires within weeks, the White House said Monday.

Bolton's nomination has languished in the Senate Foreign Relations Committee for more than a year, blocked by Democrats and several Republicans. Sen. Lincoln Chafee, a moderate Republican who lost in the midterm elections November 7 that swept Democrats to power in both houses of Congress, was adamantly opposed to Bolton.

Critics have questioned Bolton's brusque style and whether he could be an effective public servant who could help bring reform to the U.N.
