US treasury secretary Scott Bessent on Friday slammed Nvidia and commerce secretary Howard Lutnick over the ongoing spying row, saying the chip-making company had no robust controls to identify whether any spying was taking place.During an interview with CNBC, Bessent said there was significant leakage in the chip export system and that the Trump administration was working to plug those gaps.Bessent said his department was in favor of putting Megaspeed on the US entity list for months, adding that it was up to the commerce department to manage the list and that the FTC could possibly take action.“OFAC has no control over things like this, in terms of exports. This is a BIS (Bureau of Industry and Security)decision, and perhaps the FTC could put something on their restrictive list,” Bessent told CNBC.
