Booker, the former mayor of Newark, will take the oath of office administered by Biden at noon.
Booker won the special election for deceased Sen. Frank Lautenberg's (D-NJ) Senate seat roughly two weeks earlier. Booker replaces interim Sen. Jeff Chiesa (R-NJ), who was appointed by New Jersey Gov. Chris Christie (R) to fill Lautenberg's seat in June after Lautenberg's death.
The Newark Star-Ledger first reported the news of Booker's swearing in.
