This just posted by The State newspaper in Columbia:
Lt. Gov. Andre Bauer plans to call on embattled Gov. Mark Sanford to step down during a noon news conference today. Bauer will also renew his pledge to bow out of the 2010 gubernatorial race should Sanford resign within a month or so….
Bauer is the first constitutional officer to join a growing chorus of lawmakers pushing for Sanford to resign, including a majority of Republican state senators.
