BREAKING: Bernie Sanders Formally Endorses Biden

The New York Times reports:

Senator Bernie Sanders endorsed Joseph R. Biden Jr. as the Democratic nominee for president on Monday, adding the weight of his left-wing support to Mr. Biden’s candidacy and taking a major step toward bringing unity to the party’s effort to unseat President Trump in November.

In throwing his weight behind Mr. Biden, he is sending a striking and unmistakable signal that his supporters — who are known for their intense loyalty — should do so as well. Mr. Sanders hinted his intentions in a Twitter post shortly before appearing on a livestream.
