Issa: 'Fast and furious' subpoenas issued soon

A key House investigator says he could send subpoenas to the Obama administration as soon as this week over weapons lost amid the Mexican drug war.

House oversight committee chairman Darrell Issa suggested on "Fox News Sunday" that Attorney General Eric Holder knew about the gun trafficking operation known as "Fast and Furious" earlier than he has acknowledged. Subpoenas could go out as soon as this week, Issa said.

The Bureau of Alcohol, Tobacco, Firearms and Explosives in 2009 allowed intermediaries for drug cartels to buy thousands of weapons from Arizona gun shops and lost track of about 1,400 of the 2,000 of those guns. Some of those weapons have been recovered at crime scenes in Mexico.
