South Carolina Lt. Gov. Andre Bauer (R) is set to hold a press conference in a few minutes, and his office is saying he will call for Gov. Mark Sanford (R) to resign.

From the AP:
A spokesman says South Carolina's lieutenant governor will call for embattled Gov. Mark Sanford to step down.

Communications director Frank Adams says Andre Bauer will call on Sanford to resign at a news conference Wednesday. If he does, Bauer will renew his offer to stay out of the 2010 gubernatorial race and instead fill the remainder of his fellow Republican's term, which ends in January 2011.

Sanford has come under scrutiny since his June admission of an affair with an Argentine woman, and Bauer is the most prominent Republican to call for his resignation. Sanford's spokesman did not return a call for comment, but the governor has said he does not plan to resign.

Associated Press investigations have raised questions about the legality of Sanford's travel.
