Democratic leaders have requested an independent audit of the S.C. Department of Revenue after hackers stole tax information belonging to 6.4 million consumers and businesses.

The lawmaker also plan to introduce legislation for the state offer tax credits for people paying for credit-monitoring and repay people for the costs of resolving identity-theft cases.

Sen. Vincent Sheheen, a Democrat from Kershaw who was among lawmakers requesting the audit, called the hacking and the response by state officials, including Gov. Nikki Haley, “the mother of all government dysfunction” at a news conference Thursday.

The governor’s office said Sheheen, who is expected to try another run against Haley like he did in 2010, was grandstanding. “He has never uttered the word ‘cyber-security’ until this hacking incident occurred,” Haley’s spokesman Rob Godfrey said.

Still, Godfrey said the governor has no objections to an audit.
