President-elect Trump has tweeted a swipe at former President Clinton, the day after he formally beat Hillary in the electoral college.

It's a counterattack and FOX's Malini Wilkes details it:

It's push back against comments Bill Clinton made earlier this month to a small newspaper in New York. The former president said that President-elect Donald Trump doesn't know much. But one thing he does know is how to get angry white men to vote for him.

Mr. Trump took to Twitter to settle the score, saying Mr. Clinton is the one who doesn't know much. Especially how to get out the vote in swing states, even with an unlimited budget.
