Thurgood Marshall, United States v. Munoz-Flores…
“ The President can hardly be expected to search the legislative journals (if they have even been printed by the time his veto must be cast) in order to determine where to direct his veto message. Indeed, it can be said that the attestation is reasonably necessary to the operation of Art. I, § 7, cl. 1 (the Revenue-Origination Clause) , itself. The President, after all, is bound not to sign an improperly originated revenue bill by the same oath that binds us not to apply it, so he must have a ready means of knowing whence it came. ”
