On Friday, CREW filed a complaint against South Carolina Governor Mark Sanford with the South Carolina Attorney General and the State Ethics Commission, requesting an investigation into activities surrounding a surreptitious trip the governor made to Argentina.

At least one elected official in South Carolina thinks the Governor's actions may have been crimimal.

According to ABC News, a SC State Senator is seeking a criminal investigation of the Governor's actions:

Republican state Sen. Jake Knotts last week asked South Carolina prosecutors to launch a criminal probe. Today, Knotts told ABC News, he plans to pursue an investigation in the state legislature, the state attorney general’s office – and possibly a federal probe.

“When you can’t get results in your own state, there is a Justice Department in Washington,” Knotts told ABC. “I don’t want to go that route. I want us to wash our own laundry and clean up our own act.”
But he said he would if necessary.

“Somebody’s gonna look at this,” Knotts said. “Somebody’s gonna look to the bottom of it and somebody’s gonna give me some answers.”

Knotts and others accuse the governor of leaving the state to visit his mistress without turning over control, and charging taxpayers for an earlier stop in Argentina where he visited her. Sanford says he’ll repay more than $8,000 for that stop, which he says was set up by state Commerce officials.

State prosecutors say so far, there’s nothing to investigate.

“At this point we have not launched an investigation,” Reggie Lloyd, Director of the South Carolina Law Enforcement Division, told ABC. “We don’t anticipate it unless somebody brought us new facts.”

It does seem like further investigation is warranted.
