The Washington Post reports on it here: 
Federal agents and prosecutors in Phoenix ignored risks to the public
 and were primarily responsible for the botched effort to infiltrate 
weapons-smuggling rings in the operation dubbed “Fast and Furious,” according to a report released Wednesday by the Justice Department’s inspector general.
      
The long-awaited report also criticized senior officials at the
 Justice Department and its Bureau of Alcohol, Tobacco, Firearms and 
Explosives in Washington for lax oversight of the attempt to block the 
flow of weapons to Mexico’s violent drug cartels. Many of the weapons 
later turned up at crime scenes in Mexico and the United States, 
including one where a U.S. Border Patrol agent was killed.
The Hill reports that House Republicans want to see structural changes at the ATF: 
Justice Department Inspector General Michael Horowitz pleaded with 
lawmakers on Thursday to make major structural reforms at the Bureau of 
Alcohol, Tobacco, Firearms and Explosives (ATF) in the wake of a botched
 gun-tracking operation.
“There were a serious lack of controls in
 place in both the U.S. attorney's office and ATF operation,” Horowitz 
said at a House Oversight and Government Reform Committee hearing.
“There
 has to be a serious review and vetting of operations like this … and 
how to prevent that going forward, is watching carefully to make sure, 
in fact, the reforms we're all talking about aren't lost once the 
headlines of the report go away — that there is oversight.”
Committee
 Chairman Darrell Issa (R-Calif.) and ranking member Elijah Cummings 
(D-Md.) have pledged to work on reforming the ATF and the U.S. 
attorney’s office to avoid repeating the mistakes that led to Operation 
Fast and Furious. 
File this under congressional oversight and checks and balances.
