Members of the Congressional Black Caucus, some of whom may have been having a hard time getting excited about voting for Hillary Clinton, got an angry warning Saturday night about a Trump presidency from the man preparing to pack up and leave the Oval Office in January.

"I mean, he missed that whole civics lesson about slavery or Jim Crow," adding, "we will educate him." As for the black community's supposed indifference about this election, "read up on your history. It matters.
