Clapper says Samantha Powers claims about others using her name to unmask people looks improbably
...I suspect it would work by her signing off on the request for others. He needs to be brought back in for further explanation.
Interviewing Clapper about his new memoir yesterday, Hugh asked about Power’s sworn testimony that other Obama unnamed administration officials made numerous intelligence “unmasking” requests in her name. Clapper responded (my italics): “I don’t know quite how that would happen, you know, because the only way you can make an unmasking request is that you have authorized access to the report in question in the first place. So I don’t know how that, quite how that would work.”
