Via Pajamas Media, here is the LINK to Wolf's letter to Eric Holder, which says in part:
Mr. Coates has every right to bring this information to a Member of COngress as well as a responsibility to comply with the commission's subpoena, despite the department's obstruction. I trust that Mr. Coates will face no repercussion for his decision and expect you to inform political and career supervisors to respect his decision.I'd say this is the most significant blow to the repeated DOJ stonewalls that have insulated it from extremely important questions having to be answered. Depending on how explosive Coates' testimony is, we could be witnessing the beginning of the end of the Eric Holder led Justice Department.
As you are aware, the 1912 Anti-Gag Legislation and Whistleblower Protection Laws for Federal Employees guaranteed that "the right of any persons employed in the civil service...to petition Congress, or any Member thereof, or to furnish information to either House of COngress, or to any committee or member thereof, shall not be denied tor interfered with." (37 Stat. 555, 1912; codified at 5 U.S.C. 7211, 1994).
