The Obama administration is stonewalling two lawmakers’ requests to interview a former member of the National Security staff in connection with the failed Operation Fast and Furious  gun-walking program, according to a March 28 letter  obtained by The Daily Caller.
California Rep. Darrell Issa and Iowa Sen. Chuck Grassley, both Republicans, requested a response by April 4 to their letter, which asks for an interview with Kevin O’Reilly, that former staffer. But the White House, according to the letter, is blocking access to him.
Through staff, both Grassley and Issa confirmed to TheDC on Thursday that April 4 came and went without any response from the Obama administration.
In their letter to White House Counsel Karen Ruemmler, Grassley and Issa cited a cryptic email exchange between O’Reilly and William Newell, the special agent in charge of the Phoenix office of the Bureau of Alcohol, Tobacco, Firearms and Explosives at the time Fast and Furious was implemented. The emails, their letter suggests, indicate that Newell was going around his chain of command to personally brief the White House about developments in the gun-walking program.
