TikTok on Sunday raised free speech concerns over a bill passed by the U.S. House of Representatives that would ban the popular social media app from listing in the United States if its Chinese owner ByteDance does not sell its stake within a year.

The House passed the legislation Saturday by a margin of 360 to 58. The bill now heads to the Senate, where it could be voted on in the coming days. President Joe Biden has previously said he would sign the bill.

The move to include TikTok in a broader foreign aid package could speed up the timeline for a potential ban after an earlier separate bill stalled in the U.S. Senate.

“Unfortunately, the House of Representatives has once again used the guise of critical foreign and humanitarian aid to block a ban bill that would trample the free speech rights of 170 million Americans,” TikTok said in a statement.

Many U.S. lawmakers from Republicans, Democrats and the Biden administration have said TikTok poses a national security risk because China could force the company to share data on its 170 million U.S. users. TikTok insists it has never shared U.S. data and never will.

Democratic U.S. Senator Mark Warner, chairman of the Senate Intelligence Committee, said on Sunday that TikTok could be used as a propaganda tool by the Chinese government.

“Many young people get their news on TikTok (from the app), and we believe we’re giving the (Chinese) Communist Party so many propaganda tools and the ability to steal the personal data of 170 million Americans that it’s a national security risk,” he told CBS News.

Some progressive Democrats have also raised free speech concerns about the ban and called for stricter data privacy regulations.

Democratic U.S. Rep. Ro Khanna said on Sunday that he believed a TikTok ban might not survive legal review in the courts, citing the U.S. Constitution’s protection of free speech.

“I don’t think it would pass First Amendment muster,” he said in an interview with ABC News.

The House of Representatives voted on March 13 to give ByteDance about six months to divest the U.S. assets of the short video app or face a ban. The legislation passed on Saturday sets a nine-month deadline that can be extended by a further three months if the president wants to determine the progress of the sale.

TikTok was also a topic of discussion during Biden’s phone call with Chinese President Xi Jinping earlier this month. The White House said Biden raised concerns among Americans about ownership of the app.
