Did they ever turn over the fast and furious files ?
Apparently not, although Congressional committee hearings did turn up evidence of deception on the part of ATF and the DOJ, and then-Attorney General Eric Holder was held in contempt of congress, the first sitting member of a president's cabinet to achieve that distinction.
For that is all it was. No other penalty was ever meted out to Holder, who remained in office for nearly another three hears after the finding, the vote for which having been along party lines.
From all appearances, it would seem that Holder took his contempt citation as a badge of honor. Among his cronies and supporters, that's all it was.
From a Fox News story on the subject, published in June of this year (2017):
Grassley's and Dodson's testimony reinforced findings of the report, which states that the Justice Department knew before Terry’s death that the ATF was “walking” firearms to Mexico and knew the day after the agent’s death that Fast and Furious guns were involved in the shootout -- despite denying these facts to the media. It goes on to state that the Justice Department’s internal investigation focused more on spinning the story to avoid negative media coverage than looking into lapses by either the DOJ or ATF.Several emails revealed in the report appear to indicate that some Justice Department staffers were working to keep information from political appointees at the department.
“I don't want to jinx it but it really is astounding that the plan worked -- so far,” former Deputy Attorney General James Cole wrote in an email to Holder, according to the report.
The report also says that Holder’s Justice Department stonewalled inquiries from Sen. Chuck Grassley, R-Iowa, and deceptively told him that the “ATF makes every effort to interdict” firearms purchased by straw buyers. The controversial act of straw purchases – where a person who is prohibited from buying firearms uses another person to buy a gun on his or her behalf – has been a popular method that Mexico’s drug cartels use to obtain guns.
“There are important reasons for not giving Grassley everything he is asking for: it would embolden him in future fights and would 'use up' a lot of the material that we will eventually need to release to (California Rep. Darrell) Issa . . . as the oversight struggle continues,” the Office of Legislative Affairs Assistant Attorney General Ron Welch said in an email to DOJ colleagues.
