U.S. Special Counsel Robert Mueller has asked Germany's Deutsche Bank for data on accounts held by President Donald Trump and his family, according to media reports.
Citing people close to the matter, the Reuters news agency reported on December 5 that Mueller issued a subpoena to Germany's largest bank several weeks ago to provide information on certain money and credit transactions.
The subpoena was earlier reported by German newspaper Handelsblatt.
Jay Sekulow, a lawyer for Trump, said the reports were "false."
"No subpoena has been issued or received," Sekulow said in a statement. "We have confirmed this with the bank and other sources."
Deutsche Bank, which has previously rejected similar demands, citing privacy laws, said it would not comment on any of its clients.
Mueller is investigating alleged Russian attempts to influence the 2016 U.S. presidential election and potential collusion between his campaign team and the Russians.
Four people have been criminally charged in connection with the investigation, including Trump’s former national security adviser Michael Flynn and the president’s former campaign chairman Paul Manafort.
Russia denies it meddled in last year's election, despite what U.S. intelligence officials say is powerful evidence, and Trump denies there was any collusion between his associates and Russia.
