A spokesperson for the district attorney’s office in Manhattan said Thursday they were now in possession of former President Donald Trump’s tax returns, just days after the Supreme Court rejected appeals on preventing their release.

A spokesman for Manhattan District Attorney Cyrus Vance, Jr., Danny Frost, confirmed to CBS News that prosecutors had access to the tax records by Monday, the same day the high court rejected appeals filed by the former president’s legal team to keep them sealed.

Vance has been probing Trump’s financial records at least since 2018, focusing his investigations early on into hush-money paid to adult film star Stormy Daniels and Playboy model Karen McDougal to keep quiet about alleged extra-marital affairs.

The investigation has now expanded to include allegations of fraud related to the business dealings of the Trump Organization and its properties. Prosecutors allege that Trump’s business falsely inflated the value of the former president’s properties to secure the best possible loan arrangements. Those concerns extend to investigations into whether or not Trump’s company presented the proper values to tax officials.

A source familiar with the documents told ABC the tax filings are millions of pages long. They were turned over Monday by Mazars USA, the former president’s accounting firm.

Vance has already interviewed Michael Cohen, Trump’s former personal lawyer who was handed a three-year prison term after admitting to delivering the payments to Daniels and McDougal. Cohen testified before lawmakers that Trump’s company manipulated the value of his assets for tax and loan purposes, as Vance has charged.

Presidents are not required to hand over their tax documents, though presidents since Richard Nixon have. Trump continued to describe investigations into his wealth and political dealings a “witch hunt.”

"The Supreme Court never should have let this 'fishing expedition' happen, but they did," he said in a statement following Monday’s Supreme Court ruling.
