Germany's Deutsche Bank has subpoenaed for documents related to its business dealings with Donald Trump, as part of the probe into possible collusion between the US president's campaign and Russia, a source close to the matter confirmed to AFP Tuesday.

The source confirmed the subpoena by special prosecutor Robert Mueller's investigation shortly after White House spokeswoman Sarah Sanders and Trump lawyer Jay Sekulow denied that Trump's financial records had been subpoenaed from the bank.
