Despite pressure and criticism from Republicans, Attorney General Eric Holder is sticking to the story that his testimony about the "Fast and Furious" guns probe was truthful and accurate.
In 2009, Holder tried to trace illegal gun smuggling in Mexico by allowing more than 2,000 guns to get into the hands of criminals.
But the operation -- called "Fast and Furious"-- got out of hand when the Bureau of Alcohol, Tobacco, Firearms and Explosives lost track of most of the weapons.
Offcials say about 1,400 of the more than 2,000 guns in the operation were compromised. Some of the guns were recovered at crime scenes in Mexico.
Others were used to kill more than 100 Mexican citizens and two U.S. Customs and Border Proection agents.
During a congressional investigation in March, Holder said he had just learned of the problem "recently."
"I have no recollection of knowing about" the operation, Holder said again in a letter Friday to lawmakers who oversee Justice Department issues.
But Republicans say the attorney general had to have known about the operation before it made news, because weekly reports were sent on the investigation.
House Judiciary Committee chairman Lamar Smith, R-Texas, called on President Barack Obama to direct the Justice Department to appoint a special counsel to investigate.
Obama has said he has complete confidence in Holder.
