Artem Uss at center of suspected supply chain that used U.S. technology to support Putin's war in Ukraine

Artem Uss, son of a Siberian governor, was arrested last year on charges that he and his associates defrauded the US and its companies.

He's the most politically connected Russian to be indicted by the US 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.

Ukraine's government has publicly urged tech giants to stop making microchips that it says support Russia’s Glonass satellite navigation system.

Analog Devices in a statement said any post-sanctions shipments into Russia, the Russian-occupied regions of Ukraine and Belarus is a direct violation of its policies.

Texas Instruments said it doesn’t sell into Russia or Belarus and works on screening customers.

Uss faces up to 30 years in a US prison if extradited to Russia if he is extradited.

Uss’s alleged involvement in chips smuggling started in 2018, the same year his father secured election as governor of the resource-rich Krasnoyarsk region.

Russia has put the younger Uss on a wanted list for alleged money-laundering and is asking for his handover.
