Appearing with Stephen Colbert, Jill Biden responded to attacks on her doctorate and her using “Dr.” as a title.

“That was such a surprise,” Biden said of the criticism from Joseph Epstein, who wrote a controversial Op-Ed in the Wall Street Journal “and it was really the tone of it …you know, he called me ‘kiddo” and one of the things I’m most proud of is my doctorate.”

“I mean I worked so hard for it,” she added.
