US Senator Elizabeth Warren has called for immediate congressional action after reports emerged that artificial intelligence computers manufactured by Nvidia may be powering Russian drones deployed in the war against Ukraine. The Massachusetts Democrat, who serves as the ranking member on the Senate Banking, Housing and Urban Affairs Committee, said the allegations raise serious questions about whether the American chipmaker is doing enough to keep its advanced technology out of adversarial hands.

What the Allegations Claim

According to a statement released by the Democratic staff of the Senate Banking, Housing and Urban Affairs Committee, Russian drones allegedly powered by Nvidia AI computers killed three civilians in Ukraine on 6 July. Senator Warren did not identify the specific Nvidia systems allegedly found in the drones, nor did she detail how the chips may have reached Russia. The committee statement similarly offered no sourcing for the underlying reports on which the allegation was based.

Notably, Nvidia did not respond to the allegations within the committee statement, and the company's position on the matter was not included.

Warren's Demand: Huang Must Testify

Warren called on Nvidia chief executive Jensen Huang to appear before Congress and explain how the company monitors the destination and end-use of its products. In pointed remarks, she said: 'If Jensen Huang has time to attend a $1 million-a-head dinner at Mar-a-Lago and fly across the world to meet with President Xi Jinping, he can find time to testify in front of Congress about reports that NVIDIA technology is powering Russia's war machine.'

She further stated: 'These allegations raise serious questions about whether NVIDIA is taking necessary steps to ensure its technology does not end up in the hands of adversaries.'

The Broader Export Control Concern

The allegations add to growing congressional anxiety over the possible diversion of advanced American technology to Russia through intermediaries or third countries, despite existing restrictions on direct exports. Advanced AI processors and computing systems have well-documented military applications — including autonomous navigation, image recognition, target identification, and rapid processing of data collected by unmanned aerial systems.

This comes amid a pattern of concern on Capitol Hill about technology leakage: multiple investigations have found that sanctioned nations have obtained US-origin chips through circuitous supply chains involving entities in the UAE, Turkey, and other intermediary markets.

Warren's Track Record on AI and Military Use

Senator Warren has been among the most persistent voices in the US Senate pressing both the government and major technology firms on the military use of artificial intelligence. In July, she sought detailed information from the Defence Department and eight technology companies — including Nvidia — about contracts to deploy AI on classified military networks. She said at the time that the government had provided little clarity on safeguards governing such systems, including protections against civilian harm, unlawful surveillance, and the misuse of autonomous weapons.

What Congress Is Being Asked to Do

Warren explicitly called for bipartisan legislative action, saying: 'Congress needs to act now to pass bipartisan bills that will make sure our most advanced technologies are not being used to compromise our national security.' The push for stronger export controls is likely to intersect with ongoing debates over the CHIPS and Science Act implementation and broader US semiconductor policy toward China and Russia.

Whether Congress acts — and whether Jensen Huang agrees to testify — will be closely watched by the semiconductor industry and US national security officials alike.
