So why couldn't he bring himself to do it when he on TV "suspended" his campaign?

Fucking prima donna.

Bernie Sanders has announced his endorsement of Joe Biden for president, during a virtual livestream on the US response to the coronavirus pandemic.

Sanders dropped out of the Democratic primary last week.

“So today, I am asking all Americans, I’m asking every Democrat, I’m asking every independent, I’m asking a lot of Republicans, to come together in this campaign to support your candidacy, which I endorse,” the senator from Vermont said, appearing alongside Biden, who was hosting the broadcast.

“We’ve got to make Trump a one-term president,” Sanders said. 

“I will do all that I can to make that happen.”
