Alaska officials are investigating an apparent gap in last week's release of former Gov. Sarah Palin's emails, the Associated Press reported.

Alaska released 24,199 pages covering Dec. 4, 2006, when Palin took office, until September 2008, a few weeks after Republican presidential candidate John McCain tapped her to be his vice presidential running mate.

There are a very few emails from her first month in office, however, as the Anchorage Daily News first reported.

Linda Perez, the administrative office for Alaska Gov. Sean Parnell, said Tuesday she has asked information technology services to investigate. She had no timetable for an answer.
