Vice President Biden exchanged tweets with a fictional character on Thursday.

A Twitter user identified as Joshua Lyman, “Chief of Staff, Dark Prince of American Politics and 101st Senator,” sent Biden a question during a White House question-and-answer session, and the vice president replied personally.

Joshua Lyman is a fictional character played by Bradley Whitford as the deputy chief of staff to the president on the NBC drama “The West Wing,” which ran 1999-2006. The Lyman twitter account is not formally affiliated with the television show.

The faux Lyman tweeted: “Does President Obama’s proposal to keep kids in High School until 18 include an opt out for kids who want to get a GED? #whchat”

Biden tweeted: “Yes, until 18 or graduation — includes GED. But staying in school increases earning power. -vp #whchat #bestidea”
