A grandson’s not the only new thing in Sarah Palin’s life! She may also have a new political scandal brewing.

An Alaska investigator and the union representing Alaska State Troopers claim there was some political meddling in the drug investigation of Sherry Johnston, the mother of Bristol Palin’s fiancé, Levi. The couple had a baby boy, Tripp, last month.

Mrs. Johnston was busted December 18 for six drug-related felony counts, including a "second-degree misconduct involving a controlled substance," which can mean manufacturing or distributing drugs. She’s charged with selling the prescription painkiller OxyContin, but is out on bail and due in court this week.

Though investigators have been eyeing Johnston for some time, investigator Kyle Young insists the case "became anything but normal" after they realized Johnston’s connection to Palin, who was running for vice president at the time.

According to Young, the warrant for Johnston’s arrest was delayed because of the November general election.

John Cyr, executive director of the union, told the Anchorage Daily News, "This really does smack of political favoritism. And if that be the case, it’s another example of the Palin administration’s direct influence on the public safety unit."

That remark was in reference to the so-called "Troopergate" investigation, which involved allegations that Palin, her husband, Todd, and others, encouraged public-safety officials to fire her brother-in-law, who was in the middle of a nasty divorce with the governor’s sister. A report later found that Palin did in fact abuse her power a bit and let family influence that decision.

Alaska’s public-safety officials, meanwhile, claim the case was handled fairly, and promise that neither the governor nor anyone in her office knew police were investigating Johnston until the arrest warrant was served. Of course, only a thorough investigation into the investigation can reveal the truth.
