WASHINGTON -- Cory Booker will officially become New Jersey's newest Senator at noon on Oct. 31, Vice President Biden's office said Wednesday.
Booker, the Democratic mayor of Newark, won a special election last week over Republican Steve Lonegan.
He will replace Republican Sen. Jeff Chiesa, who was appointed by Gov. Christie to fill-in for the late-Sen. Frank Lautenberg. Lautenberg, a Democrat, died in office in June.
Booker will restore the Democratic majority to 55 seats, including left-leaning independents who caucus with them.
