More than a dozen state attorneys general have joined the U.S. Justice Department's investigation of the proposed acquisitions of Humana by Aetna and of Anthem's bid for Cigna Corp., according to Reuters. Florida, Iowa, Tennessee and Connecticut are among the states that have signed on with federal regulators to scrutinize the impact of the deals, the news service reported. Kentucky isn't one of them. Attorney General Andy Beshear's spokesman responded to questions by releasing a statement saying that the office "...is committed to enforcing our state's competition laws in a manner that protects Kentucky consumers. At this time, the office is not participating in the federal review."
