Commerce Secretary Howard Lutnick has agreed to appear voluntarily before the Senate Banking Committee on Dec. 10 after receiving a summons Thursday evening. Lawmakers are questioning whether Nvidia supplied advanced AI chips to Chinese companies and whether the Commerce Department failed to close export control loopholes. The move follows the Thursday resignation of Nvidia CEO Jensen Huang, who acknowledged an affair with a Megaspeed executive; the Singapore-based company bought more than $4.8 billion in advanced Nvidia AI chips over the past two years. Sen. Elizabeth Warren and Sen. Chris Coons are demanding an explanation and the preservation of all export-related documents, while Sen. Jim Banks accused Lutnick of using loopholes to allow some chip sales. Criticism is mounting against the Trump administration for leaving more than 100 companies flagged as national security risks, including DeepSeek and CXMT, off its trade blacklist.
