According to the BBC, US Treasury Secretary Scott Bessent has put responsibility on the Commerce Department for weak supervision of advanced Nvidia chip shipments abroad. The scandal is still spreading. Lutnick faces mounting scrutiny from lawmakers across the political spectrum, who want him to account for his department’s conduct.
The affair story began when Jensen Huang lost his job as Nvidia chief executive. Reports revealed he had been involved with a businesswoman, who is alleged to have been a Chinese spy. She worked at Megaspeed, a company that US government agencies investigated over claims it moved Nvidia chips into China. Reports say Megaspeed does not appear on the list of firms American businesses are barred from dealing with.

Bessent points at the Commerce Department
Speaking to CNBC, Bessent said several agencies had backed adding Megaspeed to the entity list for a long period. He added that the Commerce Department holds the final decision, so questions about how it reached that choice should go to the department itself. He also voiced irritation at the slow pace and at reports that AI chips were reaching China.
Bessent cited President Donald Trump’s position that Nvidia chips above the H100 generation should be kept from China. In his view, any leak undercuts American firms competing in artificial intelligence by handing Chinese companies an edge.
According to the New York Times, the Commerce Department opened an inquiry into Megaspeed last year over suspected smuggling of certain advanced Nvidia AI chips. Separate reporting from the Financial Times indicated that officials were dragging their feet on adding the cloud computing company to the list. Megaspeed was approached for comment.
Bessent also criticises Nvidia
Bessent did not limit his criticism to the government. He told CNBC’s Squawk Box that coverage has concentrated on Huang’s private behaviour. In his view, the central questions are whether Nvidia understood who its buyers were and whether it made a serious attempt to stop chips reaching what he called pass-through shell companies. He insisted that people at the company responsible must face consequences.
Congress opens inquiries
The Senate Banking Committee has summoned Lutnick to give evidence in the coming month. The hearing will examine his department’s part in permitting Nvidia to export advanced chips. Huang has also been summoned to testify to the same committee. Committee chairman Tim Scott, a Republican senator, posted on X that recent reports pose a threat to American security and to sensitive technology.
Other committees have asked Lutnick, his department and Nvidia to preserve every document connected to Nvidia and Huang. Democrats Richard E. Neal and Ron Wyden have opened probes into how the chip sales were approved. They say H200 chips might have reached Chinese buyers if they first travelled from Taiwan, where they were made, into the United States for checks.
A 25% charge, collected by the federal government, was applied to those chips under a clause of trade law designed to let the president respond to imports that endanger national security. Neal and Wyden argue that the president’s use of this clause seems to have produced the opposite result, weakening US security and exposing Americans to risk.
