House Judiciary Chairman Jim Jordan, R-Ohio, on Thursday announced a subpoena against Citibank seeking documents related to an investigation into major banks sharing private financial data with the FBI.

"[T]he Committee and Select Subcommittee have recently obtained documents that raise new concerns regarding the extent to which financial institutions, including Citibank, may have shared customer information with federal law enforcement despite the customers having no individualized nexus to criminal conduct," Jordan wrote to the firm. "In particular, these documents indicate that a Citibank representative was included on emails and Zoom discussions organized by the FBI and the Financial Crimes Enforcement Network (FinCEN) focused on 'identifying the best approach to information sharing, both strategic and operational,' in the wake of the events of January 6."
