Two Army soldiers stationed at Joint Base Lewis-McChord in Washington and a former soldier in Oregon have been accused in separate indictments of sharing classified military information with China, according to the Justice Department.

Justice Department prosecutors indicted three men, including two Joint Base Lewis-McChord soldiers, alleging they conspired to sell defense secrets to China.

An active-duty U.S. Army soldier stationed at Joint Base Lewis-McChord was arrested Thursday after being indicted by a federal grand jury on charges of “conspiring to obtain and transmit national defense information” to individuals in China, the U.S. Attorney’s Office reported.
