Special Counsel Robert Mueller has reportedly asked Deutsche Bank to share information related to President Donald Trump's financial transactions.
-The German bank received a subpoena from Mr. Mueller several weeks ago, the source said, confirming a report by German newspaper Handelsblatt published on Tuesday.
United States investigators are said to be demanding information on dealings linked to Mr Trump as part of an investigation into alleged Russian influence in the United States presidential election, according to Handelsblatt and Reuters.
The bank told Bloomberg, in a statement, that it had always cooperated with investigating authorities.
Deutsche Bank spokesman Chalie Olivier told Newsweek the bank declined to comment on the matter.
The bank has rejected the efforts of House Democrats to provide details of Trump and his family's finances, saying it would be illegal to share client data without a formal request.
In June, President Trump disclosed that he owes the bank roughly $130 million. Representative Maxine Waters of California and other Democrats have asked whether the bank's loans to Trump, made years before he ran for president, were in any way connected to Russian Federation.
The German bank is one of the few major lenders that has lent large amounts to Trump in the past decade.
Trump also has mortgages with the bank on his Trump National Doral Miami golf course and has borrowed off Trump Tower Chicago.
Mueller's focus on Trump campaign officials' financial dealings led to the indictment of Trump campaign Chairman Paul Manafort and his longtime associate Rick Gates, who pleaded not guilty to money laundering and a host of other financial crimes in late October.
Russian Federation has denied meddling repeatedly and Trump has denied all allegations of collusion.
