Twitter shut down Vine at the tail-end of 2016, but pledged that specific clips from certain notable accounts would remain available. Last fall, Twitter handed over a list of more than 2,750 usernames that it believed were linked to the Kremlin connected disinformation bureau the Internet Research Agency. But those accounts, including @Guns4life_me and @PoliceStateMe, had publicly-viewable clips in Vine's archive.

Since CNN's story broke, the accounts have been suspended, but it's thought that between them, videos were looped more than 14 million times. In a statement, Twitter said that had "suspended all known Vine accounts" that it was able to link to the Internet Research Agency. That doesn't seem to be good enough for the Senate Intelligence Committee's Mark Warner, who said that Twitter needs to "take responsibility and be proactive about stopping Russians and other bad actors who are abusing its platform."
