ANCHORAGE, Alaska -- Alaska officials are investigating an apparent gap in last week's release of former Gov. Sarah Palin's emails.

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

However, there are very few emails from her first month in office, as first reported by the Anchorage Daily News.

In fact, the first email generated from Palin's Yahoo account appears Jan. 2, 2007. Another from an unidentified account just days earlier was included in an email chain between aides.

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