Investigators looking into Russian election meddling have requested data on accounts held by Donald Trump and his family with Deutsche Bank, US media has reported.

Robert Mueller, the US special counsel leading the investigation, is said to have issued a subpoena to Germany’s largest bank several weeks ago.

The bank has lent Mr Trump hundreds of millions of dollars over the years for various development projects, according to property filings.

The subpoena was first reported by German newspaper Handelsblatt and confirmed by a number of other media outlets, including the news agencies Reuters and Bloomberg.

A spokesman for the lender told Bloomberg: “Deutsche Bank always cooperates with investigating authorities in all countries.”
