(CNN)—Aides to Alaska Gov. Sarah Palin improperly obtained her former brother-in-law’s state police personnel files and cited information from those records to raise complaints about the officer, the head of Alaska’s state police union said Thursday.

“It’s apparent to us that the governor or someone on her staff had direct access to his personnel file, as well as his workers’ comp file, and those are protected,” said John Cyr, executive director of the Alaska Public Safety Employees Association.
