Samantha Power sought to unmask Americans on almost daily basis, sources say
Two sources, who were not authorized to speak on the record, said the requests to identify Americans whose names surfaced in foreign intelligence reporting, known as unmasking, exceeded 260 last year. One source indicated this occurred in the final days of the Obama White House.
The details emerged ahead of an expected appearance by Power next month on Capitol Hill. She is one of several Obama administration officials facing congressional scrutiny for their role in seeking the identities of Trump associates in intelligence reports – but the interest in her actions is particularly high.
