Kentucky Democratic Senate nominee Jack Conway may have tipped off his brother about an ongoing drug trafficking investigation involving said brother.

Jack Conway, the Democratic attorney general of Kentucky who is running for U.S. Senate, says he was not involved in a recent criminal investigation involving his brother and drug trafficking.

But it appears he — along with other law enforcement officials — tipped his brother off about the investigation.

The campaign made a statement distancing Conway from his brother’s investigation in a Saturday story in Louisville’s Courier-Journal. The story was the first to disclose this summer’s drug probe.

In August, authorities decided not to file charges against Conway’s brother, Matthew Conway, according to the report.

The story notes how a supporter who overheard a narcotics detective speaking about the investigation alerted Jack Conway. Conway’s campaign says the attorney general subsequently aided his brother in getting an attorney.

The Courier-Journal also says two detectives accused of leaking the fact that an investigation was taking place to Matthew Conway have been placed on administrative leave until it’s determined whether they violated any policies.

Conway has some serious questions to answer. Shouting “Aqua Buddha” isn’t a sufficient response to these troubling allegations.
