Citing an anonymous source informed about the subpoenas, The Times reported that the New York Attorney General's Office, Letitia James, had opened a new investigation based on the testimony of Donald Trump's former lawyer, Michael Cohen , in front of Congress last month. The investigation is a civil inquiry and not a criminal investigation, the Times said, adding that its scope and purpose were unclear.
Cohen testified that Trump had inflated his holdings and submitted copies of the financial statements which, he said, were provided to Deutsche Bank.
Investigators asked the German lender for financial documents regarding the Trump International hotel in Washington, the Trump National Doral outside Miami, the Trump International Hotel and the tower in Chicago, as well as unsuccessful attempts to purchase the BFL Buffalo Bills, the Times reported.
Investors Bank, based in New Jersey, "has been cited for Trump Park Avenue documents" in Manhattan, the Times reported.
CNN contacted the New York Attorney General's Office and Investors Bank. Deutsche Bank declined to comment.
Deutsche Bank is already the subject of a joint investigation between House Financial Services and the intelligence commissions on Trump activities and money laundering involving Russia.
The highest committee democrats are interested in Deutsche Bank because it is one of the few major banks willing to lend to the Trump Organization. Trump companies have borrowed more than $ 300 million from Deutsche Bank to finance golf courses and hotels in Chicago and Chicago, Florida, according to financial information and public reports released between 2012 and 2015.
