Financial records related to U.S. President Donald Trump and three of his children that congressional Democrats have requested from Deutsche Bank AG include tax returns, the bank disclosed in a court filing on Tuesday.

Two committees in the U.S. House of Representatives subpoenaed Deutsche Bank in April to provide financial records belonging to the president and his children Donald Trump Jr., Ivanka Trump and Eric Trump.

Deutsche Bank's filing, in the 2nd U.S. Circuit Court of Appeals, revealed that it had tax returns that it would need to hand over if it complied with the subpoenas, which the Trumps are seeking to block. It was not clear whose tax returns it had, because names were redacted from the filing.
