President-elect Joe Biden is tapping Samantha Power to lead the U.S. Agency for International Development.
The agency oversees the nation's foreign humanitarian projects.
Power previously served the Obama administration as the U.S. ambassador to the United Nations.
She won a Pulitzer Prize in 2003 for her book about the U.S. foreign policy response to genocide.
In a statement, Biden lauded Power as "a voice of conscience and moral clarity."
