Republican Rep. Chip Limehouse says in a letter sent Tuesday to the State Law Enforcement Division he has questions about how Alvin Greene came up with the more than $10,000 needed to file as a U.S. Senate candidate.
Greene is represented by a public defender on a felony obscenity charge. Limehouse says Greene may owe the government money if it's proven he didn't need a publicly paid lawyer.
Greene has said he saved up for two years to pay the candidate fee.
Greene stunned state party leaders last week when he defeated a former state lawmaker in the primary to face Republican Sen. Jim DeMint.
