Manhattan prosecutors won an important court victory in their fraud investigation into Donald Trump’s businesses after the US Supreme Court declined the former president’s attempt to block a subpoena of his financial records.Prosecutors had argued in court filings that Mr. Trump’s effort to keep his tax and financial records secret posed a notable obstacle to their complex financial investigation into possible bank, insurance and tax fraud. Now, the district Attorney’s office will possibly obtain the records from Mr. Trump’s accounting firm, Mazars USA LLP, within days, former prosecutors said. Manhattan district Attorney Cyrus Vance’s office hasn’t stated publicly what it anticipates to find in Mr. Trump’s tax records. Former prosecutors stated that they might want to compare information on the tax records with document they have already acquired Mr. Vance’s office has subpoenaed information regarding Mr. Trump’s lenders and an insurer. Prosecutors also subpoenaed the New York City Tax Commission, which handles tax appeals, a city spokeswoman confirmed. They may be keeping a look out for discrepancies between information submitted to tax authorities and financial authorities, which could point investigators to potential red flags. Knowingly submitting false information to a financial institution, and acquiring specific loans as a result, can be a New York State crime, former prosecutors said.
