Web of secret chip deals allegedly help U.S. tech flow to Russia

Artem Uss, son of a Siberian governor, was arrested last year on charges of defrauding the U.S. and its companies.

He's the most politically connected Russian to be indicted by the U., as Washington races to choke off Moscow’s access to chips used in weapons systems.

Uss has denied any wrongdoing and is now in the midst of an extradition battle in Milan.
