Democrat Jon Ossoff has defeated Republican David Perdue in the Georgia runoff, The Associated Press said Wednesday, giving Democrats control of the U.S. Senate.

Ossoff is the first Jewish senator from Georgia and will be the youngest sitting U.S. senator at age 33. His victory comes along with the historic win of Raphael Warnock, who will take office as the state’s first Black senator. They are the first Democrats to win Senate seats in Georgia since 2000.

It will take several days for the Georgia runoffs to be officially certified, so they will not take office immediately.

The Senate would be evenly divided between Democrats and Republicans, but once sworn in as vice president, Kamala Harris would have the power to break ties for Democrats.
