The U.S. Senate on Tuesday voted to confirm President Joe Biden's nomination of Linda Thomas-Greenfield, a veteran diplomat, to serve as the U.S. ambassador to the United Nations.

The Senate approved her nomination by a vote of 78-20, making Thomas-Greenfield the eighth official to join Biden's cabinet. With Thomas-Greenfield's confirmation, Biden's foreign policy team has mostly taken shape.

Thomas-Greenfield, a 68-year-old African American, served as assistant secretary of state for African affairs in the State Department from 2013 to 2017.
