Yes and Yes

Why do they need to waste more money on an investigation? His salary comes from the taxes of the people of South Carolina, so he used taxpayer money because it was on their time. If the lieutenant governor knew where he was, then he lied, and he should go too. Any money Sanford uses to "pay it back" also belongs to his wife, who helped get him where he is today--the governor's mansion. If I were her I'd clamp that bank account, safe deposit box, automobile, real estate, stock ownership and house shut like yesterday. She and the children should not have to pay for his catting around and it's expensive to raise children through college when you've just lost your job. She should learn from Mrs. Edwards' example.

"Democratic leaders want an investigation into Sanford's use of state money to help pay for an earlier South America trip. Others are questioning whether the governor broke laws by leaving without giving the lieutenant governor control." AP report
