CHARLESTON, S.C. —
Colbert Busch's campaign ad says she worked to provide trained workers for the Boeing plant in North Charleston and that Sanford knew it. The ad came after an earlier Sanford ad questioned her claim she "worked with Boeing."
"It's the same Mark Sanford who used tax dollars to visit his mistress in Argentina," the Colbert Busch ad says. "He disappeared for a week leaving no one in charge. He betrayed all who trusted in him and then lied to cover it up."
Before leaving office, Sanford avoided impeachment but was censured by the Legislature over state travel expenses he used for the affair. He also paid the largest ethics fine ever in South Carolina, $70,000.
Sanford did not respond directly to the new attacks or the billboard.
The ad from the House Majority PAC shows a woman who claims she is a lifelong Republican saying she could not vote for Sanford.
"I used to be for Mark Sanford but not anymore. He skipped town to be with his mistress on Father's Day. Sanford even asked his wife for permission to have the affair and wasted our taxpayer dollars on himself. I'm a Republican, but Mark Sanford just does not share our values," says the woman, Jennifer Stark of Mount Pleasant.
Sanford and his wife Jenny have divorced, and the ex-governor is now engaged to his former mistress, Maria Belen Chapur, who even appeared at his victory speech after the GOP primary runoff.
In April, Jenny Sanford accused him in a court complaint of repeatedly trespassing in her home. The revelation prompted the National Republican Congressional Committee to pull its support from Sanford's campaign. Sanford has said he went there because he didn't want his 14-year-old son to have to watch the Super Bowl alone.
