DONALD J. TRUMP, ET AL., PETITIONERS 
v. 
DEUTSCHE BANK AG, ET AL. 

ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF 
APPEALS FOR THE SECOND CIRCUIT 

[July 9, 2020]

 CHIEF  JUSTICE  ROBERTS  delivered  the  opinion  of  the 

Court. 

Over the course of five days in April 2019, three commit-
tees of the U. S. House of Representatives issued four sub-
poenas seeking information about the finances of President 
Donald  J.  Trump,  his  children,  and  affiliated  businesses. 
We have held that the House has authority under the Con-
stitution to issue subpoenas to assist it in carrying out its
legislative responsibilities.  The House asserts that the fi-
nancial information sought here—encompassing a decade’s
worth of transactions by the President and his family—will 
help guide legislative reform in areas ranging from money
laundering  and  terrorism  to  foreign  involvement  in  U. S.
