Twitter said Wednesday 1.4 million people may have interacted with fake Russian accounts on its site. That's a pretty big increase from the roughly 678,000 it reported Monday.
Twitter said in a statement those people "potentially connected to a propaganda effort by a Russian government-linked organization known as the Internet Research Agency."
The interactions would have taken place in the 10 weeks leading up to the 2016 presidential election.
Twitter says those 1.4 million users followed, retweeted, liked, mentioned, quoted or replied to 3,814 accounts that it's since linked to the IRA.
Twitter has been working with Congress to identify Russian influence on its website. So far, the company has identified more than 50,000 Russian-linked automated accounts.
