From NBC's Mark Murray
Mark Sanford's office has announced that the South Carolina governor -- "taken aback by all of the interest" in his trip -- will return to work tomorrow.
Said spokesman Joel Sawyer in an e-mail to reporters:
Governor Sanford called to check in with his Chief of Staff this morning. It would be fair to say the governor was somewhat taken aback by all of the interest this trip has gotten.
Given the circumstances and the attention this has garnered, the governor communicated to us that he plans on returning to the office tomorrow.
