Senior U.S. District Judge Victor Marrero of the Southern District of New York on Thursday pressed attorneys for President Donald Trump to demonstrate whether they have new information about the potential flaws in a Manhattan grand jury subpoena for the president's tax records.

Trump's lawsuit against his accounting firm and Manhattan District Attorney Cyrus Vance Jr. returned to Marrero's courtroom this month after the U.S. Supreme Court found, in a 7-2 ruling, that the president was not immune from investigation in state court.

Trump's attorney William Consovoy of Consovoy McCarthy plans to file an amended complaint by July 27, he wrote in a joint letter to Marrero this week. Carey Dunne, who is general counsel in Vance's office, said during a conference Thursday that the office intends to "immediately" file a motion to dismiss the complaint.
