President Donald Trump says New York Attorney General Letitia James is “closely coordinating with House Democrats in a joint effort to obtain and expose” the president’s tax returns and financial information.

The allegation came in a filing Monday in federal district court in Washington as Trump amended the July 23 lawsuit he brought to block James and Michael R. Schmidt, commissioner of New York state’s Department of Taxation and Finance, from providing the president’s state tax returns to the House Ways and Means Committee.

As evidence, the president’s filing cited the state attorney general’s issuing of “several” subpoenas — “some of which are not yet public” — seeking the same information as subpoenas from the House Ways and Means Committee.

Trump also argued against a motion by the state officials to send the case to a federal district court in New York or dismiss it entirely. In the amended complaint, Trump argued the dispute belongs inside the Beltway.
