The House committee has not identified the Trump people who were unmasked. Nor has it identified the “one official” who made those hundreds of requests. But it’s pretty obvious this was Samantha Power, Barack Obama’s ambassador to the United Nations. In May the House Intelligence Committee subpoenaed the unmasking requests from Ms. Power, former CIA director John Brennan and former National Security Adviser Susan Rice.

Ms. Power is the only one of those three whose job had no clear intelligence-related function. The plot got even thicker when the committee asked for the same unmasking records for Ben Rhodes. He was the hyper-political Obama Deputy National Security Adviser who last year gleefully boasted to the New York Times how he’d manipulated reporters to sell Mr. Obama’s nuclear deal with Iran.
