At the time, under the Bush administration Department of Justice (DOJ), no arrests or indictments were made. After President Barack Obama took office in 2009, the DOJ reviewed Wide Receiver in September 2009 and found that guns had been allowed into the hands of suspected gun traffickers. Indictments began in 2010, over three years after Wide Receiver concluded. As of October 4, 2011, nine people had been charged with making false statements in acquisition of firearms and illicit transfer, shipment or delivery of firearms. As of November, charges against one defendant had been dropped; five of them had pled guilty, and one had been sentenced to one year and one day in prison. Two of them remained fugitives.
Another, smaller probe occurred in 2007 under the same ATF Phoenix field division. It began when the ATF identified Mexican suspects who bought weapons from a Phoenix gun shop over a span of several months. The probe ultimately involved over 200 guns, a dozen of which were lost in Mexico. On September 27, 2007, ATF agents saw the original suspects buying weapons at the same store and followed them toward the Mexican border. The ATF informed the Mexican government when the suspects successfully crossed the border, but Mexican law enforcement were unable to track them.
Less than two weeks later, on October 6, William Newell, then ATF's special agent in charge of the Phoenix field division, shut down the operation at the behest of William Hoover, ATF's assistant director for the office of field operations.
 No charges were filed. Newell, who was special agent in charge from June 2006 to May 2011, would later play a major role in Operation Fast and Furious.
