WASHINGTON (AP) — President Barack Obama's choice as U.N. ambassador says if she's confirmed by the Senate, she'll work to eliminate what she calls the United Nations' "unacceptable bias and attacks" on Israel.

Samantha Power says she'll also work to make the U.N. more efficient and stand up for freedom.

Power has been criticized by some groups for past comments considered critical of Israel.

Still, the former journalist and human rights activist is expected to be confirmed.

The Irish-born Power told the Senate Foreign Relations Committee on Wednesday that the U.S. has no "greater friend" than Israel.

She criticized the U.N. for its "disproportionate" focus on Israel.

Power also said the Security Council's failure to stop Syria's civil war is a "disgrace that history will judge harshly."
