The government has settled with two whistleblowers at the center of an infamous gun tracking operation. Larry Alt and Olindo "Lee" Casa blew the whistle on Operation Fast and Furious at the Justice Department. They claimed retaliation by their home agency — the Bureau of Alcohol, Tobacco, Firearms and Explosives. The Office of Special Counsel won't say what the settlement involves. Another whistleblower settled with ATF last month.
