President Obama delivered a civics lesson Wednesday when he said he’s offended that Donald Trump’s rhetoric is being described as “populist,” and described his own view of what populism means.

“Maybe someone can pull up in a dictionary quickly the phrase populism, but I’m not prepared to concede the notion that some of the rhetoric that has been popping ” can be described as populism, he said. Obama said he sought the presidency in 2008 and 2012 “because I care about people, and I want to make sure everybody in America has the same opportunities that I have.”
