For all the controversy that has plagued the U.S. Department of Justice under Attorney General Eric Holder Jr., from terror-trial venues to voting and immigrant rights issues, nothing has had more sticking power than the botched gun-trafficking probe called Operation Fast and Furious.

If Holder was hoping the flap over Fast and Furious would quietly subside, that hasn’t happened. And it isn’t likely. The congressional inquiry into the flawed program will continue into the new year and the Justice Department hasn’t wrapped up its internal investigation.
