During the Congressional Black Caucus Foundation dinner, President Obama discussed issues of civil rights and slavery in relation to Donald Trump.

Addressing the Congressional Black Caucus gala for the last time as president, Obama warned that while his name would not be on the ballot in November, all of the progress that the country has made over the last eight years was on the line.

“If I hear anybody saying their vote does not matter, that it doesn’t matter who we elect — read up on your history. It matters. We’ve got to get people to vote,” Obama said. “I will consider it a personal insult — an insult to my legacy — if this community lets down its guard and fails to activate itself in this election. You want to give me a good sendoff? Go vote.”
