Two congressmen say a classified Pentagon report on former National Security Agency contractor Edward Snowden says most of the documents he took concerned current military operations.

House Intelligence Chairman Mike Rogers, R-Mich., and ranking Democrat C.A. Dutch Ruppersberger of Maryland say Snowden tipped off U.S. enemies to spying methods used to defend the country, and potentially jeopardized U.S. troops overseas.

They say the classified report by the Defense Intelligence Agency found that Snowden stole approximately 1.7 million intelligence files that “concern vital operations of the U.S. Army, Navy, Marine Corps, and Air Force.”

Quoting the report, the lawmakers say the disclosures have already tipped off U.S. adversaries to U.S. defense methods, and hurt U.S. allies helping with counterterrorism, cybercrime, trafficking, and stopping weapons of mass destruction. They offered no specifics.
