(HP)–According to the New York Daily News, Epstein and the woman had a three-year sexual relationship and often exchanged “twisted text messages.”

The Spectator reports that Epstein is married to another Columbia political science professor, Sharyn O’Halloran, though a recent update to his Facebook page says he is single. The couple was featured in a 2008 Spectator article about professors who “bring love to work.”

“Our complementary skills lead to a great partnership,” O’Halloran told the Spectator.

One student described Epstein, who was teaching a class on game theory this semester, as a “very nice guy.” Outside of his professorial duties, Epstein also blogged for this website, on topics ranging from torture to Sarah Palin.

Epstein is currently on administrative leave.
