Judicial Watch sued the State Department last year to obtain access to the Clinton emails and to force the State Department to recover missing emails. The Trump State Department (Tillerson) has opposed Judicial Watch's request to force the State Department to recover the emails. This is relevant because the NYPD chief confirmed that the Clinton related emails includes evidence of child sexual abuse and trafficking.
