Cook is the first ever black American woman in this post.

The U.S. Senate has confirmed Lisa Cook as a member of the Board of Governors of the Federal Reserve System. Cook, an economics professor at the University of Michigan, will be the first African-American woman to hold the post.

Sherrod Brown, head of the U.S. Senate Banking Committee, called Cook’s approval “historic” and stressed that she would be able to open up “invaluable prospects.” The Republican leader on the committee, Patrick Toomey, said he feared that Cook would not effectively fight inflation.

None of the Republicans supported Cook’s candidacy: 50 senators voted in support of her, 50 against. The decisive vote was cast by U.S. Vice President Kamala Harris, who, according to the Constitution, is also the president of the Senate.
