Weeks after Donald Trump was elected president, Russia-backed online “trolls” flooded social media to try to block Mitt Romney from securing a top job in the incoming administration, a Wall Street Journal analysis shows. The operatives called the 2012 GOP presidential nominee, then a contender for secretary of state, a “two headed snake” and a “globalist puppet,” promoted a rally outside Trump Tower and spread a petition to block Romney’s appointment to the top diplomatic job, according to a review of now-deleted social-media posts.

Leveraging social media, Russians have collected data by peddling niche business directories, convincing activists to sign petitions and bankrolling self-defense training classes in return for student information. It isn’t clear for what purpose the data were collected, but intelligence and cybersecurity experts say it could be used for identity theft or leveraged as part of a wider political-influence effort that didn’t end with the 2016 election.
