(WFXR) — Virginia Senator Mark Warner is leading an effort to restrict technology that has ties to foreign adversaries.

He announced the Restricting the Emergence of Security Threats that Risk Information and Communications Technology (RESTRICT) Act in a press conference on Tuesday, March 7 alongside a bipartisan team of senators backing the bill. Chinese-owned social media app TikTok was a particular focus of the meeting.

TikTok has already been banned on government devices in the U.S., Canada, and the European Union, but concerns persist about the app’s data collection.

“Over the past several years, foreign technology products from adversarial nations, and when I say adversarial nations, I’m specifically citing China, Russia, North Korea, Iran, Cuba, and Venezuela, have really tried to establish a foothold in American markets,” said Warner.

If passed, the RESTRICT act would allow the president and secretary of commerce to restrict tech platforms that pose a threat to security.

His chief concern is that foreign adversary, the Chinese Communist Party, is getting their hands on Americans’ data through TikTok. The app’s owner, ByteDance, says they do not give data to their government, but at the press conference, U.S. senators repeatedly questioned that claim.

“It was reported last year that China-based employees of ByteDance have repeatedly accessed non-public data about users in the U.S. despite TikTok saying to the contrary,” said Sen. John Thune, who worked alongside Warner on the bill.

Mary Hamilton, CEO of Mad Data explains why data matters.

“Most people use the same passwords across multiple platforms to get into their bank, to get into their grocery stuff, to sign up for TikTok,” she said.

She says a video-driven app like TikTok has your biometrics too, meaning the measurements of your face that you might use to open your phone or get into a banking app. All that information can be used to access your accounts.

“If you look at security from a national standpoint, how many databases are protected by biometrics? Whether it’s your retina scan, facial scan, fingerprints, any of that information,” she said.

The legislation doesn’t just take aim at TikTok; if it’s passed, Warner says it will allow a holistic approach for tech coming from the U.S.’s adversarial nations.
