Questions about how quickly Mexicans were informed about "Wide Receiver" Program

The Obama Justice Department does seem to make clear that in the beginning the Wide Receiver guns were not meant to go to Mexico. Once they realized that was the case, the Bush Administration tried looping in Mexican authorities. When did the Obama administration try to bring in Mexican authorities? This from the left-wing TPM:

One of the distinctions that Republicans have drawn between Operation Fast and Furious, the flawed investigation that allowed weapons to “walk” into Mexico during the Obama administration, and Operation Wide Receiver, which did the same during the Bush administration, is that authorities who took part in the earlier investigation were coordinating their efforts with Mexican authorities.

“The difference in the previous administration is there was coordination with the Mexican government,” Rep. Darrell Issa (R-CA) said at a hearing in December. “They made a real effort under Wide Receiver to pass off a small amount of weapons and track them.”

But new documents DOJ disclosed to congressional investigators on Thursday appear to indicate that ATF officials didn’t even consider looping Mexican authorities in on their operation until several months after the investigation began and ATF had already lost track of weapons that likely ended up in Mexico. . . .

Later previously disclosed documents — from September 2007, well into the investigation that started in early 2006 — show that ATF officials were coordinating with Mexican authorities but they were unsuccessful in intercepting traffickers crossing the border and allowed weapons to flow into Mexico. Attorney General Eric Holder acknowledged that officials worked with Mexican officials during Operation Wide Receiver. . . .

Issa spokesman Frederick Hill said in a statement. “There is, however, a distinction between them and efforts to coordinate with the Government of Mexico versus Fast and Furious where there was a proactive effort to keep the Mexican government and U.S. Mexico City Embassy in the dark.” . . .
