The National Rifle Association (NRA) is gathering documents in preparation for a possible investigation into its connections to a Kremlin-tied banker, CNN reported Friday.

Staffers have been directed to collect documents that mention banker Alexander Torshin or his associate, Maria Butina, who runs a pro-gun group in Russia, the network reported.

Congressional investigators have already pressed the gun group over its links to Torshin, a lifetime NRA member and the deputy governor of Russia’s central bank.
