TikTok to Challenge Trump Administration Over Executive Order

SAN FRANCISCO — TikTok plans to sue the United States government, the company confirmed on Saturday, arguing that President Trump’s moves to block the app had deprived it of due process and claiming it had been unfairly and incorrectly treated as a security threat.

The lawsuit, which the company plans to file next week, would amount to the most public pushback against the United States by TikTok, which is owned by the Chinese internet company ByteDance.

“Even though we strongly disagree with the administration’s concerns, for nearly a year we have sought to engage in good faith to provide a constructive solution,” Josh Gartner, a TikTok spokesman, said in a statement. “What we encountered instead was a lack of due process as the administration paid no attention to facts and tried to insert itself into negotiations between private businesses.”

For weeks, Mr. Trump has railed against TikTok and its ties to China, arguing that the app was a national security threat and that it could share data about its users with the Chinese government. On Aug. 6, Mr. Trump issued an executive order against TikTok, saying it would ban transactions with the app within 45 days. A week later, he issued a separate executive order giving ByteDance 90 days to divest from its American assets and any data that TikTok had gathered in the United States.
