Manhattan District Attorney Cy Vance wants a federal judge to block President Trump’s attempts to keep his office from subpoenaing his corporate and personal tax returns.

Trump sued Vance in Manhattan federal court last week after the DA’s office served Mazars USA for eight years worth of returns as part of an investigation into hush-money payments made to Stormy Daniels and Karen McDougal by Trump’s former fixer Michael Cohen.

Prosecutors on Monday argued a judge should toss the lawsuit — writing that Trump’s claims lack merit and “rely on the remarkable proposition that a sitting President enjoys not only a blanket immunity from criminal prosecution.”

“The plaintiff’s position is that none of this conduct, unrelated to the office of the President, can be investigated while the President remains in office,” Vance’s office wrote. “That this blanket immunity also protects a president from having to respond to any routine, lawful grand jury request for information about his conduct or that of his businesses or employees before he took office.”

The Trump Organization willingly turned over more than 3,376 pages of other relevant documents, “but no tax returns,” the filing says.

Sources speculated last week — based on the time range targeted by the Mazars subpoenas — that Vance’s office is also probing matters other than the hush-money payments.

The parties are due in court Wednesday for oral arguments.
