## Facts

- Three House committees issued four subpoenas in April 2019 to Mazars USA, LLP, Deutsche Bank, and Capital One seeking extensive personal financial records of President Donald J. Trump, his family, and affiliated entities.
- The committees stated legislative objectives including possible reforms to ethics and financial disclosure laws and inquiries related to foreign influence, money laundering, and related matters.
- The records sought were personal, held by third-party custodians, and were not claimed to be protected by executive privilege.
- President Trump, in his personal capacity and with related family members and entities, sued to block compliance, arguing the subpoenas lacked a valid legislative purpose and raised separation-of-powers concerns.

## Issues

1. Under what standard may a congressional committee subpoena a sitting President’s personal, nonprivileged financial records from third-party custodians.
2. Whether the subpoenas exceeded the House’s constitutional authority by insufficiently accounting for separation-of-powers concerns.

## Decision

- The Supreme Court, in a 7–2 decision by Chief Justice Roberts, vacated the judgment enforcing the subpoena and remanded.
- The Court rejected the House’s position that ordinary, highly deferential legislative-subpoena standards apply without modification when a subpoena targets the President’s personal records.
- The Court rejected the President’s proposed near-categorical rule requiring a “demonstrably critical” showing akin to certain criminal-process standards.
- The Court announced a heightened, four-consideration framework that lower courts must apply to assess congressional subpoenas for a President’s personal information.
- The Court did not decide whether the specific subpoenas were ultimately enforceable; it required reconsideration under the new framework.

## Legal Principles

- Congress’s investigative power, including subpoenas, is valid only when used “in aid of” legislation; Congress may not use subpoenas for law-enforcement purposes assigned to the Executive and Judiciary.
- Courts must account for separation-of-powers concerns when Congress seeks a sitting President’s personal records, even when held by third parties and not covered by executive privilege.
- In evaluating such subpoenas, courts should consider:
  - Whether the asserted legislative purpose justifies involving the President and whether the information is available from other sources.
  - Whether the subpoena is no broader than reasonably necessary for the stated legislative objective.
  - The quality and nature of Congress’s evidence that the subpoena advances a valid legislative purpose, guarding against exposure or harassment for its own sake.
  - The burdens on the Presidency and whether the political branches attempted negotiation and accommodation before seeking judicial enforcement.

## Conclusion

The Court held that congressional subpoenas for a sitting President’s personal financial records require heightened judicial scrutiny grounded in separation-of-powers principles, vacated the lower-court enforcement ruling, and remanded for application of a four-factor balancing framework rather than ordinary deferential review or a near-immunity rule.
