South Carolina Democrat Alvin Greene, who prompted widespread speculation about his Senate candidacy after an upset win in the state's primary, was charged today with showing pornography to a college student.

Greene, who won 59% of the Democratic primary vote on June 8 despite having not done any traditional campaigning or fundraising, was arrested in November for allegedly showing obscene photos to a student in a University of South Carolina computer lab.

A grand jury in Richland County, S.C., indicted Greene on one felony charge of disseminating, procuring or promoting obscenity as well as a misdemeanor charge of communicating obscene materials to a person without consent, according to a statement from the county solicitor's office.

An unemployed military veteran, Greene has faced repeated questions from reporters about his campaign and about how he raised the $10,000 fee needed to put his name on the ballot. Fellow South Carolina Democratic Rep. Jim Clyburn called for an investigation into Greene's campaign.

An investigation last month by the South Carolina Law Enforcement Division found that Greene's story checked out: The bulk of the money had come from Greene's exit pay from the military and a tax refund.

Greene will face Republican Sen. Jim DeMint in November.
