NEW YORK (AP) — New York Attorney General Letitia James is challenging the legitimacy of the acting U.S. attorney in Albany as she pushes back against the Trump administration’s investigation of cases she brought against the president and the National Rifle Association, according to court documents unsealed Friday.

James in August filed a motion to block subpoenas issued by acting U.S. Attorney John Sarcone for records related to the legal actions, claiming the Justice Department’s probe of the cases was retaliatory.

She also argued that Sarcone had been improperly appointed to his position and, as a result, lacked legitimate authority to authorize the subpoenas.

The subpoenas seek records related to a major civil case the Democrat James filed against President Donald Trump over alleged fraud in his personal business dealings. Another subpoena seeks records from a lawsuit involving the National Rifle Association and two senior executives.

Dozens of court documents in the case have been filed under seal in U.S. District Court since August. A federal judge in Manhattan late Friday granted James’ motion to unseal most of the entries, making them public over the objection of the Justice Department.

Judge Lorna Schofield, however, has not yet ruled on the motion to quash the subpoenas.
