More than half a year after the IRS targeting scandal broke in May, federal investigators have still not contacted any of the 41 conservative groups represented in the American Center for Law and Justice (ACLJ) lawsuit against the IRS.

Though the FBI and IRS both launched investigations into the wrongdoing, and Eric Holder’s Justice Department vowed to cooperate with the FBI probe, none of these agencies have contacted the ACLJ’s clients to figure out what happened.

“It’s now been more than six months since the public revelation of the IRS targeting scheme. The Obama Administration — including the White House — has repeatedly promised that an investigation would ensue and that we would get to the bottom of this unlawful and unconstitutional scheme. Unfortunately, that does not appear to be happening. To date, not one of our 41 clients has been contacted by the FBI, the Justice Department or any other federal investigative agency,” ACLJ chief counsel Jay Sekulow told The Daily Caller.
