National Democratic sources pointed to recent events at Wayne State University as an underlying cause for Benson's decision. Earlier in the fall, a law student was murdered.
"Over the past month there has been a great deal of media speculation about local and national efforts to recruit me for a possible bid for Congress," Benson wrote in an email to Wayne State University faculty. "While I am touched by the efforts of people in the 11th Congressional District to encourage me to represent them in Washington, my priority is leading the Law School as Interim Dean. For that reason, I want you to know that I will not be a candidate for Congress in 2014."
