Federal prosecutors investigating former FBI Director James Comey have determined that a key witness, Professor Daniel Richman, would be "problematic" for their case. Richman reportedly told investigators Comey never authorized him to leak information anonymously to the press. Despite securing an indictment on charges of making false statements, officials privately believe the case could quickly falter under legal scrutiny. Prosecutors concluded their investigation with a memo recommending against charging Comey due to "likely insurmountable problems" in proving he knowingly misled Congress.
