(NEW YORK POST) — Federal authorities are investigating whether sensitive data was stolen from congressional offices by several Pakistani-American tech staffers and sold to Pakistani or Russian intelligence, knowledgeable sources say.

What started out 16 months ago as a scandal involving the alleged theft of computer equipment from Congress has turned into a national-security investigation involving FBI surveillance of the suspects.

Investigators now suspect that sensitive US government data — possibly including classified information — could have been compromised and may have been sold to hostile foreign governments that could use it to blackmail members of Congress or even put their lives at risk.
