Prosecutors in Boston have moved to drop the case after new information came to light, including an interview with a high-level Department of Energy official, according to the person familiar with the case. The decision was reported earlier Friday by The Wall Street Journal and The Washington Post.
Two of Chen's lawyers, Robert Fisher and Brian Kelly, declined to comment Friday.
Despite a conviction last month of a Harvard University professor on charges that he hid his ties to a Chinese-run recruitment program, other high-profile cases have faltered.
A federal judge in September, for instance, threw out all charges against a University of Tennessee professor accused of hiding his relationship with a Chinese university while receiving research grants from NASA, and the university has since offered to reinstate him.
