Senators summon Nvidia's Huang and Commerce's Lutnick over China security concerns

Former Nvidia CEO Jensen Huang and Commerce Secretary Howard Lutnick have been summoned to testify before the Senate Banking Committee next month over national security concerns tied to Huang's affair with a suspected Chinese spy. Sen. Tim Scott sent letters Thursday requesting testimony, citing "serious concerns about our national security and the protection of sensitive U.S. technology." Huang resigned as CEO Thursday, but bipartisan leaders, including Sen. Chuck Schumer, are demanding answers about whether he compromised security and what the Trump administration knew. Huang has hired lawyers experienced in government investigations. House Republicans are also in talks with him to testify before other committees, while Democrats are probing Lutnick's department's review of Nvidia's advanced chip sales to China.
