Congressional investigators have subpoenaed Deutsche Bank as Democrats stepped up their investigations into Donald Trump and his business dealings.
The subpoenas from the US House of Representatives intelligence and financial services committees marked an escalation of Democratic-led probes into Mr Trump’s finances and his businesses.
The committees also subpoenaed multiple other banks as part of their investigations into foreign influence in US politics and illicit finance.
Adam Schiff, the Democratic chairman of the House intelligence committee, confirmed the subpoenas in a statement on Monday night. The New York Times first reported the document requests.
“The House intelligence committee today issued subpoenas to multiple financial institutions in co-ordination with the House financial services committee, including a friendly subpoena to Deutsche Bank, which has been co-operative with the committees,” Mr Schiff said.
Maxine Waters, who chairs the House financial services committee, said: “The potential use of the US financial system for illicit purposes is a very serious concern.”
She added her committee was “exploring these matters, including as they may involve the president and his associates, as thoroughly as possible pursuant to its oversight authority”.
A Deutsche Bank spokesperson said the German lender was in a “productive dialogue” with the committees.
“We remain committed to providing appropriate information to all authorised investigations in a manner consistent with our legal obligations,” the spokesperson said.
The White House referred queries to the Trump Organization.
In a statement, Eric Trump, Mr Trump's son and an executive at the Trump Organization, called the Deutsche Bank subpoena "an unprecedented abuse of power and simply the latest attempt by House Democrats to attack the President and our family for political gain".
