Trump sues Manhattan DA to block tax return subpoena

NEW YORK -- President Donald Trump asked a federal court Thursday to block an effort by New York prosecutors to obtain his tax returns as part of a criminal investigation, opening another front in the president's efforts to keep his financial information private.

Trump's attorneys filed a lawsuit against Manhattan District Attorney Cyrus R. Vance Jr., who recently subpoenaed the president's accounting firm for eight years of his state and federal returns as part of an investigation into payments made to two women who claimed to have had affairs with Trump.

They called the subpoena a "bad faith effort to harass" Trump and said Vance, a Democrat, had overstepped his constitutional authority.

"Virtually 'all legal commenters agree' that a sitting President of the United States is not 'subject to the criminal process' while he is in office," Trump's lawyers wrote. "Yet a county prosecutor in New York, for what appears to be the first time in our nation's history, is attempting to do just that.

The lawsuit, filed in Manhattan federal court, asks U.S. District Judge Victor Marrero to declare the subpoena unenforceable until Trump leaves office.

Trump lawyer Jay Sekulow said the lawsuit is intended "to address the significant constitutional issues at stake in this case."

A spokesman for Vance said his office had received the lawsuit "and will respond as appropriate in court." Trump's accounting firm, Mazars USA, declined to comment.

Meanwhile, Democratic-led congressional committees are also trying to obtain Trump's tax returns and other records that could provide a window into his finances. Trump and three of his children filed a lawsuit in April seeking to block two House committees from getting records his longtime lender, Deutsche Bank, has said include tax returns.

And in July, the president sued to block a new New York law that could allow a House committee to obtain his state tax returns.

Unlike those efforts, Vance's investigation is conducting a criminal probe. His subpoenas were issued by a grand jury.

The grand jury also subpoenaed the Trump Organization for records related to payments former Trump lawyer Michael Cohen helped arrange to the porn actress Stormy Daniels and model Karen McDougal during the 2016 presidential campaign to keep either woman from speaking publicly about alleged affairs with Trump. He made one of the payments himself and arranged for American Media Inc., the parent company of the National Enquirer, to make the other.

Cohen pleaded guilty to federal charges the payments amounted to illegal campaign contributions. Federal prosecutors did not charge Trump or anyone else involved in either arranging the payoffs or reimbursing Cohen through Trump's company.

Trump has denied any sexual relationship with either woman and said any payments were personal matters, not campaign expenses.
