(AP) -- Governor Mark Sanford's lawyer has told the South Carolina Ethics Commission that required disclosures weren't filed on four of 61 flights investigators questioned as part of their investigation of the governor's travel and campaign finance practices.

Kevin Hall's admission is included in nearly 1,400 pages released by Sanford's lawyers earlier this week. It came as the House began an impeachment hearing that could end the two-term Republican's second and final term, which ends in January 2011.

Four flights in 2006 weren't reported as he campaigned for re-election. His lawyers said those were inadvertent and unintentional and amounted to technical issues.

The commission's 37 charges against Sanford don't include the flights because Sanford belatedly reported them.
