What are the requirements of Section 1951(a) of the Criminal Code requiring proof of a potential impact on interstate commerce?

Here both of the challenged instructions accurately stated the requirements of 1951(a) by requiring proof of a potential impact on interstate commerce. Instruction number 29 required proof of a "probable or potential" impact on interstate commerce, tracking the language of several of the above cases. Instruction number 26, requiring that commerce "was or would have been affected" by the robbery, also required a potential impact and tracked the language of United States v. Pascucci, 943 F.2d 1032 (9th Cir.1991).
