Former United Nations Ambassador Samantha Power is believed to have made "hundreds" of unmasking requests to identify individuals named in classified intelligence community reports related to Trump and his presidential transition team, according to multiple sources who said the behavior is unprecedented for an official in her position. Power was first identified by the Washington Free Beacon last month as a central figure in a congressional investigation into efforts by senior Obama administration officials to obtain classified intelligence information in what many allege was an effort to undermine President Donald Trump and his incoming national security team.
