The former president’s accountants will give New York prosecutors the financial records he has spent years trying to shield.

WASHINGTON — The Supreme Court on Monday rejected a last-ditch attempt by former President Donald J. Trump to shield his financial records, issuing a brief, unsigned order that ended Mr. Trump’s bitter 18-month battle to stop prosecutors in Manhattan from poring over his tax returns as they investigate possible financial crimes.
The court’s order was a decisive defeat for Mr. Trump, who had gone to extraordinary lengths to keep his tax returns and related documents secret, taking his case to the Supreme Court twice. There were no dissents noted.
From the start, Mr. Trump’s battle to keep his returns under wraps had tested the scope and limits of presidential power. Last summer, the justices rejected Mr. Trump’s argument that state prosecutors cannot investigate a sitting president, ruling that no citizen was above “the common duty to produce evidence.” This time, the court denied Mr. Trump’s emergency request to block a subpoena for his records, effectively ending the case.
The ruling is also a big victory for the Manhattan district attorney, Cyrus R. Vance Jr., a Democrat. He will now have access to eight years’ worth of Mr. Trump’s personal and corporate tax returns, as well as other financial records that Mr. Vance’s investigators view as vital to their inquiry into whether the former president and his company manipulated property values to obtain bank loans and tax benefits.
