Judicial Watch is suing the Office of the Director of National Intelligence for access to documents related to a senior adviser who resigned due to close ties with a Chinese company seen as an espionage threat.

The adviser, Theodore Moran, left the DNI’s office last September after officials learned he had served China-based Huawei Technologies as a paid consultant since 2010. His resignation came after Rep. Frank Wolf, R-Va., complained to Director of National Intelligence James Clapper that Moran’s work with Huawei “compromises his ability to advise your office.”
