A watchdog group wants South Carolina's top prosecutor to investigate whether someone gave money to the unemployed, unknown Democrat who won the U.S. Senate primary last week.
Citizens for Responsibility and Ethics in Washington also filed a complaint Tuesday with the Federal Election Commission accusing Alvin Greene of failing to file appropriate campaign paperwork.
GOP State Attorney General Henry McMaster's office did not immediately respond to messages seeking comment. Greene hung up the phone when reached at home.
Greene stunned state party leaders June 8 when he defeated a former state lawmaker in the primary to face Republican U.S. Sen. Jim DeMint. Losing candidate Vic Rawl has filed a protest, saying there was a malfunction of some kind in last Tuesday's election.
