WASHINGTON — Former Democratic presidential candidate Sen. Cory Booker of New Jersey has endorsed former Vice President Joe Biden. Booker announced on Twitter early Monday that Biden will “restore honor to the Oval Office and tackle our most pressing challenges.”

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

The answer to hatred & division is to reignite our spirit of common purpose.@JoeBiden won’t only win – he’ll
show there's more that unites us than divides us.

He’ll restore honor to the Oval Office and tackle our most pressing challenges.

That’s why I’m proud to endorse Joe. pic.twitter.com/RcsnZs5mfQ

“The answer to hatred & division is to reignite our spirit of common purpose,” Booker tweeted.

His decision follows recent Biden endorsements by several failed Democratic presidential candidates, including Sen. Kamala Harris of California and former Massachusetts Gov. Deval Patrick. Former Biden rivals Amy Klobuchar, Pete Buttigieg, Beto O’Rourke, Mike Bloomberg, Tim Ryan and John Delaney have also endorsed him.

Vermont Sen. Bernie Sanders has been endorsed by Marianne Williamson and Bill de Blasio.
