US spy agencies intercept and unmask congressional figures as often as once a month

The Gang of Eight includes the House speaker and minority leader, the Senate Republican and Democratic leaders and the bipartisan heads of both chambers" intelligence committees.

Often though, the affected lawmakers or congressional aides aren’t told about the unmasking, unless it involves a security or hacking threat. So some affected lawmakers may not know about their appearance in unredacted executive branch intelligence reports, according to intelligence community sources, who spoke only on condition of anonymity.
