A trio of US lawmakers has introduced new legislation that aims to ban TikTok from operating in the United States.

The new bill by Sen. Marco Rubio, the top Republican on the Senate Intelligence Committee, and a bipartisan pair of congressmen in the House, reflects the latest escalation by US policymakers against the Chinese-owned short-form video app. TikTok has faced doubts about its ability to safeguard US user data from the Chinese government.

The proposed legislation would “block and prohibit all transactions” in the United States by social media companies with at least one million monthly users that are based in, or under the “substantial influence” of, countries that are considered foreign adversaries, including China, Russia, Iran, North Korea, Cuba and Venezuela.

The bill specifically names TikTok and its parent, ByteDance, as social media companies for the purposes of the legislation. Rubio and one of the House sponsors of the bill, Wisconsin Republican Rep. Mike Gallagher, had indicated their intention to introduce the bill in a Washington Post op-ed last month.

The legislation comes as a wave of states led by Republican governors has introduced state-level restrictions on the use of TikTok on government-owned devices. In the past two weeks, at least seven states have introduced such measures, including Maryland, South Dakota and Utah.

The flurry of activity contrasts with the lengthy negotiations TikTok has been having for years with the US government on a potential deal that may allow the company to address the national security concerns and to continue serving US users.

“The federal government has yet to take a single meaningful action to protect American users from the threat of TikTok,” Rubio said in a statement. “There is no more time to waste on meaningless negotiations with a CCP-puppet company. It is time to ban Beijing-controlled TikTok for good.”

“It’s troubling that rather than encouraging the Administration to conclude its national security review of TikTok, some members of Congress have decided to push for a politically-motivated ban that will do nothing to advance the national security of the United States,” Hilary McQuaide, a spokesperson for TikTok, said in a statement.

“We will continue to brief members of Congress on the plans that have been developed under the oversight of our country’s top national security agencies—plans that we are well underway in implementing—to further secure our platform in the United States,” McQuaide added.

TikTok has previously said it doesn’t share information with the Chinese government and that a US-based security team decides who can access US user data from China. TikTok has also previously acknowledged that employees based in China can currently access user data.

Tuesday’s bill is not the only federal legislation to target TikTok. Last year, US lawmakers proposed a law that would ban TikTok usage by federal agencies, and Rubio introduced a bill that would force some app makers to disclose ownership information. Another bill introduced this fall would prohibit TikTok from allowing China-based employees to access the user data of US citizens.

Already, the US military, the State Department and the Department of Homeland Security have restricted TikTok from devices under their control. (CNN)
