A person familiar with Mueller's investigation told the news agency Reuters on Tuesday that Germany's largest bank received a subpoena from the United States special counsel several weeks ago to provide information on certain money and credit transactions, confirming a report by German daily Handelsblatt published on the same day.
What we do know is that the Russian Federation investigation has led Mueller to Trump's personal finances, which provide a target-rich environment if you suspect financial malfeasance.
Deutsche Bank, the largest bank in Germany, has lent the Trump organisation hundreds of millions of dollars for real estate deals.
Special Counsel Robert Mueller was said to have subpoenaed Deutsche Bank for the release of Trump's medical records.
Reports of the subpoena come after Mr Trump's former national security adviser, Michael Flynn, last week admitted he had lied to the FBI over his contact with Russia's ambassador and agreed to cooperate with Mr Mueller's investigation.

The Giants organization struggling is an understatement; the team has been marked with injuries and player discontent. Reese's almost 11-year tenure ends with a 90-82 record, two Super Bowl championships (2007 and 2011).
The special counsel is investigating whether the Trump campaign colluded with Russians connected with the Kremlin in the lead-up to the 2016 election.
Russian Federation has denied meddling in the election and Mr Trump has said there was no collusion.
As Mueller's investigation unfolds, Trump has gone on the offensive.
The president declined to say what he would do if Mueller began such an examination, but he continued, "I think that's a violation". Deutsche Bank spokesman Chalie Olivier told Newsweek the bank declined to comment on the matter. "Look, this is about Russian Federation". In 2008 Trump sued the bank to get out of $40 million in guarantees he had made them on his loan.
In June Deutsche Bank cited privacy laws when it rejected a request by House Democrats to provide details of Trump's finances. The one exception was Deutsche Bank, to which Trump owed $364 million as of the end of a year ago. He has announced criminal charges against four people so far, including Trump's former national security advisor, Michael Flynn, who pleaded guilty to lying to the Federal Bureau of Investigation. In October, the first indictments in his probe were unsealed in court against Trump's former campaign manager Paul Manafort and an aide, Rick Gates. The special counsel has hired a small army of attorneys - 17 - to work the investigation.
