Berlin, December 6 (RHC)-- A U.S. federal investigator probing Russia's alleged interference in the 2016 presidential elections has reportedly called on Germany's Deutsche Bank to provide financial accounts of President Donald Trump. 

According to reports, the German bank was ordered to provide documents on its business dealings with the U.S. president as part of an investigation into possible collusion between Trump's campaign and Moscow. 

The federal investigator, who spoke on condition of anonymity, confirmed that Germany's largest bank had received a subpoena from special prosecutor Robert Mueller several weeks ago to provide information on certain money and credit transactions. 

The revelation came shortly after White House spokeswoman Sarah Huckabee Sanders and Trump's lawyer, Jay Sekulow, denied reports that Mueller had requested financial information from Deutsche Bank. 

"We have confirmed that the news reports that the special counsel had subpoenaed financial records relating to the president are false," Sekulow said in a statement.  "No subpoena has been issued or received. We have confirmed this with the bank and other sources," he added. 

Trump has on several occasions expressed support for improving relations with Washington's former Cold War foe since he started running for president. 

According to public documents, Deutsche Bank has lent more than 300 million dollars to entities affiliated with Trump's real estate empire. Trump is currently under fire for possible links between his 2016 presidential campaign and Moscow.
