THE IRS SCANDAL, DAY 778: “Now it turns out that 422 backup tapes from the crucial period were routinely erased by IRS workers. The tapes were destroyed in March 2014, according to the Treasury inspector general for the IRS, J. Russell George. That is long after lawmakers started trying to obtain all of Ms. Lerner’s emails, and long after the IRS issued instructions for employees to cease routine destruction of documents that might relate to the probes.”

Unexpectedly.
