What you need to know about the FBI’s ‘Fast and Furious’ investigation

FBI agents and prosecutors in Washington have opened an investigation into whether any of the money from the sale of guns to Mexican drug cartels came from a gun show in Arizona.

The Justice Department says it has requested that the Federal Bureau of Investigation open a criminal probe into whether the transactions violated the Arms Export Control Act, which prohibits the U.S. government from selling arms to foreign countries that may be involved in human rights abuses.

The AP has learned the Justice Department is investigating whether the sales violated the law by knowingly selling guns to a foreign country that could be involved with human rights violations.

The investigation could be conducted by the FBI or the Bureau of Alcohol, Tobacco, Firearms and Explosives, which is conducting the investigation.

The U.K.-based company that runs the gun show, Brawlers Sporting Goods, told the AP it was cooperating with the investigation and had no immediate comment.

In a statement Friday, BRAWLS SAVINGS said the company has not been notified of any inquiry by the Justice and FBI Departments.

The company has also said it is cooperating with both agencies.
