Humana (HUM +0.8%) says it's fired its lobbying firm and launched an internal probe into the circumstances surrounding the leak of a significant change in Medicare Advantage rates earlier this month. The probe will focus on determining whether the company's interests were harmed by the ties between an outside lobbyist employed by HUM and an investment firm that received a 'heads-up' and sent out early word of the policy shift to its clients. That alert set off a surge in shares of HUM and other insurers just prior to the session's close.
