 On October 31, 2011, after the release of subpoenaed documents, Assistant Attorney General Lanny Breuer stated he found out about gunwalking in Operation Wide Receiver in April 2010, and that he wished he had alerted the deputy or the attorney general at the time.The following day, in testimony before the Senate Judicial Committee in a hearing on International Organized Crime, when asked if he had reviewed the letter before it was sent to Senator Charles Grassley on February 4, 2011, denying gunwalking, Breuer replied, "I cannot say for sure whether I saw a draft of the letter that was sent to you.What I can tell you, Senator, is that at that time I was in Mexico dealing with the very real issues that we're all so committed to."
