TikTok CEO Shou Zi Chew will testify before Congress. Here’s what to know

TikTok’s chief executive is set to go toe-to-toe with lawmakers on Thursday morning, a culmination of years of back-and-forth over whether the Chinese-owned app can be trusted.

It will likely be the grilling of a lifetime for Shou Zi Chew. Arguing that one of the world’s most popular apps is a national security threat, the Biden administration is pushing for TikTok to be sold to an American company, and a bipartisan slate of lawmakers have stepped up efforts to ban the app.

TikTok and its leaders have argued against those moves, launching a campaign to convince U.S. officials that the popular video app has no ties to the Chinese government, which U.S. officials claim can manipulate the app to further its interests.

Observers have referred to Chew’s willingness to testify before Congress as a “death wish.” But Chew says the grilling is a necessary step to restore trust in one of the world’s most valuable technology companies.
