Social media company Meta—the parent company of Facebook, Instagram, and WhatsApp—announced Monday that it will ban RT and other Russian state media from its apps worldwide, days after the State Department announced sanctions against Kremlin-coordinated news organizations.

“After careful consideration, we expanded our ongoing enforcement against Russian state media outlets: Rossiya Segodnya, RT and other related entities are now banned from our apps globally for foreign interference activity,” Meta said in a statement provided to TIME.

Before the ban, RT had over 7 million followers on Facebook, while its Instagram account had over a million followers.

The move is an escalation of actions Meta announced in 2022, after Russia’s invasion of Ukraine, to limit the spread of Russian disinformation, which at the time included labeling and demoting posts with links to Russian state-controlled media outlets and demonetizing the accounts of those outlets and prohibiting them from running ads. The company also complied with E.U. and U.K. government requests to restrict access to RT and Sputnik in those territories. In response, in March 2022, Russia blocked access to Facebook and Instagram in the country. 

Meta’s latest actions come after Secretary of State Antony Blinken said in a press conference on Friday that the U.S. government has concluded Rossiya Segodnya and five of its subsidiaries, including RT, “are no longer merely firehoses of Russian Government propaganda and disinformation; they are engaged in covert influence activities aimed at undermining American elections and democracies, functioning like a de facto arm of Russia’s intelligence apparatus.” Sanctions unveiled Friday were imposed on RT’s parent company TV-Novosti as well as on Rossiya Segodnya and its general director Dmitry Kiselyov, and the State Department issued a notice “alerting the world to RT’s covert global activities.” Russian President Vladimir Putin’s spokesperson, Dmitry Peskov, told the Associated Press that the State Department’s allegations were “nonsense.”

Meta’s new global ban follows a similar YouTube global ban on Russian state-funded media channels, while TikTok and X (formerly Twitter) block access to RT and Sputnik in the E.U. and U.K.

“Well I’ve heard that recently, I’ve been on the For You page, so I thought I’d get on here myself,” Vice President Kamala Harris said in her new personal account’s first post on TikTok, the Chinese-owned short-form video platform on which she’s become a seemingly overnight sensation since launching her campaign for President earlier this week.

Within six hours of joining TikTok on Thursday, Harris had already amassed more than one million followers.

President Joe Biden’s presidential campaign in February created a campaign TikTok account, @bidenhq, which was rebranded earlier this week to @KamalaHQ and has since more than quadrupled in followers to over 1.6 million.

“Our job as a campaign is to break through the noise and make sure we’re talking to voters wherever they are—TikTok is one of those landscapes, and we’re leaving no stone unturned,” deputy campaign manager Rob Flaherty told People in a statement on Thursday. “Getting the Vice President up on TikTok means she’ll be able to directly engage with a key constituency in a way that’s true and authentic to the platform and the audience.”

Harris’ nascent presidential campaign and its supporters have leaned into the new presumptive Democratic nominee’s social media virality, embracing “brat” and “coconut tree” memes in an apparent attempt to engage with younger voters that’s already appearing to pay dividends.

According to a new Axios/Generation Lab poll, among 18- to 34-year-olds, Harris has more than triple the lead over Trump (+20%) compared to what Biden had (+6%).

Harris joins TikTok—which Trump joined in June—as the platform has come under increasing bipartisan scrutiny in the U.S., largely due to security concerns about its Beijing-based parent company ByteDance.

Harris told ABC News in a March interview that the Biden-Harris administration doesn’t plan to ban TikTok, which she said has “very important” benefits, including as a platform for people to make money and share information. “We need to deal with the owner and we have national security concerns about the owner of TikTok, but we have no intention to ban TikTok,” she said.

However, Biden signed into law in April a bill that requires ByteDance to divest its stake in TikTok, which the company has said it will not do, within a year or face a ban in the U.S.
