President Barack Obama “could not be prouder” of his former vice president, Joe Biden, for his White House win, he said Saturday.

“We’re fortunate that Joe’s got what it takes to be President and already carries himself that way,” Obama wrote — a not-so-subtle dig at President Donald Trump — in an effusive statement of congratulations posted to Twitter.

“I know that he’ll do the job with the best interests of every American at heart, whether or not he had their vote,” he said of the presumptive president-elect.

The tweet zoomed from 114,000 to 150,000 likes in just 20 seconds, minutes after Obama posted it.
