Lawyers with the office of New York County District Attorney Cyrus Vance Jr. on Thursday urged a federal judge to turn back a challenge to a grand jury subpoena seeking President Donald Trump’s tax returns from his personal accounting firm.

Vance’s office fired back at the position taken by the U.S. Department of Justice, arguing the case is ready to be decided on the merits, one day after U.S. Justice Department lawyers filed papers urging deliberate consideration of Trump’s claims in a suit over his subpoenaed tax returns.
