Jaw Sekulow denied reports that prosecutors working for the special counsel issued a subpoena to Deutsche Bank for records of Trump's business dealings.
"We have confirmed that the news reports that the Special Counsel had subpoenaed financial records relating to the President are false," Jay Sekulow said in a statement to NBC News. "No subpoena has been issued or received. We have confirmed this with the bank and other sources."
A number of news organizations, including Bloomberg, Reuters and The Wall Street Journal, reported early Tuesday that prosecutors demanded records from the German lending giant in recent weeks.
The president has said that inquiries into his financial dealings would be a "violation" of the special counsel's mandate. Mueller is investigating ties between the president's top advisers and Russia.
Trump has repeatedly denied accusations that his campaign colluded with the Russian government.
Press secretary Sarah Sanders on Tuesday called the reports that Mueller subpoenaed Deutsche Bank "totally false."
"I think this is another example of the media going too far too fast," she told reporters at a press briefing.
Sol Wisenberg, a leading white collar attorney who served as deputy independent counsel in the Whitewater investigation, said it's typical for the subject of a subpoena — in this case, the president —to be informed that prosecutors sought his records.
Wisenberg said that there are some rare circumstances in which the bank would be prevented from telling the person.
Earlier on Tuesday a Deutsche Bank spokesperson told NBC, "DB takes its legal obligations seriously and remains committed to cooperating with authorized investigations into this matter."
The lender declined to say what constituted an authorized investigation, and whether the Mueller inquiry was included.
