Multiple publications reported this week that Mueller's team had subpoenaed Deutsche Bank for that information, though some of the reports were later amended to say that investigators had asked the bank for data on Trump associates' accounts.

Jay Sekulow, a member of the president's legal team, denied that any subpoena was issued. A US official told Reuters that at the heart of the inquiry was whether the bank sold part of Trump's debt to the Russian bank VEB or any other Russian banks under sanctions. During the transition period last December, Kushner met with the head of VEB, Sergei Gorkov, in New York City.
