UNITED NATIONS (Reuters) - United States interests, including national security, would be harmed if the country retreats from a leading role at the United Nations, U.S. Ambassador Samantha Power warned on Thursday amid a backlash among Washington lawmakers against the world body.

President-elect Donald Trump also disparaged the United Nations after the Security Council adopted a Dec. 23 resolution demanding an end to settlement building by U.S. ally Israel. Trump questioned the value of the organization, while some Republican lawmakers threatened to cut crucial U.S. funding.
