Jon Ossoff has become the youngest Democrat to be elected as a US senator since Joe Biden in 1973.
Ossoff, 33, unseated incumbent Republican Sen. David Perdue in one of two runoff elections in Georgia, according to a projection early Wednesday by Decision Desk HQ and Insider.
Ossoff is also the first millennial to be elected to the Senate. The youngest sitting US senator is the Missouri Republican Josh Hawley, who is 41.
Ossoff previously worked as a US House staffer and is the CEO of an investigative-documentary company.
