Cross this possibility off the list: a federal official said Saturday that Sarah Palin is not under federal investigation. After the Alaska governor and political firebrand resigned suddenly on Friday, rumors were swirling that the FBI might be investigating her for a scandal she was preempting with her resignation."There is absolutely no truth to those rumors that we're investigating her or getting ready to indict her," Special Agent Eric Gonzalez said. Palin recently criticized the media for its speculation on her resignation on Facebook. "And though it's honorable for countless others to leave their positions for a higher calling and without finishing a term, of course we know by now, for some reason a different standard applies for the decisions I make," she wrote.
