What is the burden of a defendant challenging the sufficiency of the evidence underlying his conviction at trial?

1. A defendant challenging the sufficiency of the evidence underlying his conviction at trial "bears a heavy burden" because our standard of review is "exceedingly deferential": we "must view the evidence in the light most favorable to the government, crediting every inference that could have been drawn in the government's favor," and we will uphold the judgment if "any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt." United States v. Coplan, 703 F.3d 46, 62 (2d Cir. 2012) (internal quotation marks omitted).
