According to Bloomberg, he owes the bank about $300 million.
In June, Deutsche Bank rejected demands by US House Democrats to provide details on Trump's finances.
Trump's biggest lender, followed the orders of a subpoena to turn over all documents relating to ties with the Trump family, according to the report. A string of bankruptcies at his hotel and casino businesses during the 1990s made most of Wall Street wary of extending him credit.
Mueller is probing reported Russian attempts to influence the 2016 U.S. presidential election and potential collusion by Trump advisers.
White House press secretary Sarah Huckabee Sanders also said the reports were false. Trump told the New York Times in July that the special counsel looking into his and his family's finances would cross a red line, so we have officially entered uncharted territory in this investigation. "No subpoena has been issued or received".
Trump has more debt with Deutsche Bank than any other lender. Asked whether it was normal to give money to a customer who was a bad credit risk and a litigant, one former senior Deutsche Bank staff member said: "'Are you fucking kidding me?'"

Earlier this year, Mr Trump said pursuing his personal finances would be a breach of Mr Mueller's role as special counsel.
As Mueller's investigation unfolds, Trump has gone on the offensive.
An internal review conducted by Deutsche Bank showed no connection between those transactions and Trump, but now Mueller's squad of investigators will make their own judgment.
Trump told the New York Times this past summer he would consider it a "violation" if Mueller were to expand the probe beyond Russian Federation. The only conclusion that we can arrive at with any certitude is that Trump is kidding himself if he thinks this investigation will conclude by the end of the year. "I would say yes". The former real-estate baron has done billions of dollars' worth of business with Deutsche Bank over the past two decades, and First Lady Melania, daughter Ivanka and son-in-law Jared Kushner are also clients.
