Booker endorses Biden, says he'll 'restore honor' to office

Former Democratic presidential candidate Sen. Cory Booker of New Jersey has endorsed Joe Biden

Booker ended his own presidential bid in January, pledging to do “everything in my power to elect the eventual Democratic nominee for president."

Booker's decision follows recent Biden endorsements by several failed Democratic presidential candidates, including Sen. Kamala Harris of California and former Massachusetts Gov. Deval Patrick.
