(Politico) Rep. Darrell Issa issued a subpoena Friday for Ambassador Thomas Pickering to sit for a taped interview, but not to testify publicly before the full House Oversight Committee.

On Wednesday, Chairman Issa (R-Calif.) responded to a letter from Pickering volunteering to appear before the committee, saying that he needed to submit to a taped interview before he could testify.

Democratic Ranking Member Rep. Elijah Cummings (Md.) quickly blasted the subpoena as “extreme Republican overreach.”

It’s the latest in a back-and-forth about witnesses testifying before Issa’s committee in a series of hearings on Benghazi.
