The formation of a large group to scrutinize Aetna Inc's plan to buy Humana Inc and Anthem Inc's bid for Cigna Corp complicate what is already expected to be a tough and lengthy review by federal antitrust enforcers.
Connecticut, Florida, Iowa, Massachusetts and Tennessee are among the states that have joined forces to investigate the proposed deals, according to sources close to the states, who spoke to Reuters over recent days. Antitrust probes are designed to determine if a merger would lead to higher prices or otherwise hurt consumers.
