What is the evidence that supports the argument that the criminal activity committed by John Kubick, the former director of an investment bank, was a criminal enterprise that resulted in his own criminal conviction?

supported in the record. The criminal activity that Kubick orchestrated and from which he primarily benefitted spanned eight years and several states; included attorneys, friends, accountants, his daughter and his wife, all of whom he recruited; and involved the sham ownership of numerous properties, millions of dollars in assets, and laundering of proceeds to Kubick through a Mexican company. It was plainly extensive, and the district court was not clearly erroneous in adjusting Kubick's offense level upward on account of it. See United States v. Avila, 95 F.3d 887, 889 (9th Cir. 1996) (application of leadership adjustment reviewed for clear error).
