McConnell said that was a “attempt to scapegoat some folks out in Cincinnati.”

“Basically all we’ve gotten from the IRS, on the other hand, is an attempt to scapegoat some folks out in Cincinnati,” McConnell said on the Senate floor Wednesday. “Well, most folks don’t think that ignoring the Constitution is simply a ‘mistake.’ ”

McConnell said that he believes people higher up knew about what people in the Ohio IRS office were doing when they testified before Congress.

“The administration needs to make witnesses available to testify on this and on any other incident of targeting the administration’s ideological opponents, and to resist the temptation to stonewall or obfuscate what took place,” McConnell said. “If the president is truly concerned about this issue, as he claims, he’ll work openly and transparently with us to get to the bottom of this.”

McConnell also said new developments have made him more concerned. He pointed to reports that a liberal group called ProPublica was given applications for tax-exempt status from the IRS, which is prohibited.
