TikTok CEO Shou Zi Chew will testify before the U.S. Congressional Energy and Commerce Committee in March as lawmakers scrutinize the Chinese video-sharing app, Reuters reports.

Chew will testify March 23, which will be his first appearance before a congressional committee, committee chair Cathy McMorris Rodgers said Monday.

The House Foreign Affairs Committee plans to vote in February on a bill aimed at blocking the use of TikTok in the United States on national security grounds.

TikTok said Friday that calling for an outright ban on TikTok is a piecemeal approach to national security and a piecemeal approach to broad industry concerns such as data security, privacy and online harm.

Congresswoman McMorris Rodgers and other Republican lawmakers have demanded more information from TikTok. They want to know about its impact on young people amid concerns about harmful content, and they want more details about the potential sexual exploitation of minors on the platform, the congressmen said in a statement.

For three years, TikTok, which has more than 100 million American users, has tried to assure Washington that American citizens' personal data could not be accessed and that its content could not be manipulated by the Chinese Communist Party or anyone else influenced by Beijing.

The Committee on Foreign Investment in the United States (CFIUS) ordered ByteDance to sell TikTok in 2020 because of concerns that U.S. user data could be shared with the Chinese government.

CFIUS and TikTok negotiated for more than two years, trying to reach a national security agreement to protect U.S. TikTok users' data.
