What is the burden on a defendant to challenge their conviction on grounds of insufficiency?

A defendant bears a "heavy burden" in challenging his conviction on grounds of insufficiency. United States v. Medina, 32 F.3d 40, 43 (2d Cir.1994). The evidence must be viewed in the light most favorable to the government, "drawing all reasonable inferences and resolving all issues of credibility in its favor." Id. If the evidence suffices to convince any rational trier of fact beyond a reasonable doubt, then the conviction must stand. United States v. Resto, 824 F.2d 210, 212 (2d Cir.1987).
