Twitter has turned over the names of 201 accounts to Senate investigators who are looking into Russia’s efforts to influence the last year’s presidential election, according to the Associated Press.

The AP says that the account names are “linked to Russian attempts at influencing the 2016 presidential election,” and that they were handed over earlier this week. The handles were reportedly not revealed until now because of legal issues. Last month, Twitter announced that it suspended nearly Russia-linked 200 accounts that spread propaganda and misinformation, some of which corresponded to similar accounts identified by Facebook.
