Five members of the U.S. House of Representatives were matched against Watson at Jeopardy. Democrat Rush Holt (a nuclear physicist and former five time Jeopardy champ) came out on top. Four other representatives (two Democrats and two Republicans) were bested by Watson, with Republican Nan Hayworth attributing her loss to a “slow-clicker.”
