Fox News: "Lawmakers question Justice investigator's independence in Fast and Furious probe"

Has the outcome of the DOJ investigation into Fast & Furious already been determined? From Fox News:

Two top Republican lawmakers are questioning the independence of the Obama administration investigator tasked with probing Operation Fast and Furious, saying it appears her office is choosing not to interview high-level political employees in the Justice Department.
Rep. Darrell Issa of California and Sen. Charles Grassley of Iowa wrote a letter Thursday to Cynthia Schnedar, inspector general at the Justice Department, suggesting the office could be shielding close aides to Attorney General Eric Holder from scrutiny.
"Apparently, despite the advanced stage of its review, your office has not interviewed several key figures in Fast and Furious," they wrote of the controversial and defunct gunwalking operation undertaken by the Bureau of Alcohol, Tobacco, Firearms and Explosives, or ATF.
The lawmakers asked why it appears Schnedar has failed to interview three deputy attorneys generals, all appointees close to Holder. They are worried Schnedar's report, which is expected later this year, will avoid casting blame on the Justice Department. . . .
