Commerce Secretary Howard Lutnick said Thursday that TikTok will go dark for Americans unless China agrees to give the U.S. more control over the popular short-form video app. "We've made the decision. You can't have Chinese control and have something on 100 million American phones," Lutnick told CNBC's "Squawk on the Street" on Thursday. TikTok's future in the U.S. has been uncertain since 2024, when Congress passed a bill that would ban the platform unless its Chinese owner, ByteDance, divested from it. Lawmakers had grown concerned that the Chinese government could access sensitive data from American users or manipulate content on the platform.
