New Fast and Furious Report
From the House Oversight Committee. It features lots of details about who-knew-what-when.
From the executive summary:
The Criminal Division was not the only component of the Justice Department overseeing Fast and Furious. The Office of the Deputy Attorney General was also involved. Acting Deputy Attorney General Gary Grindler and his staff were briefed extensively on the enormous volume of firearms involved in the case. Individuals in that office, including Ed Siskel, received constant updates on recoveries of large numbers of weapons connected to Fast and Furious.
Though many senior Department officials were keenly aware of Fast and Furious, no one questioned the operation. The Southwest Border Strategy Group asked no questions. The Criminal Division asked no questions. The Office of the Deputy Attorney General asked no questions. No one ordered that Fast and Furious be shut down. Instead, senior Department officials let it continue to grow.
