U.S. Rep. Jim Langevin, who owns Facebook stock worth at least $300,000, said he supports imposing stronger regulation of the social media giant.

A financial disclosure form filed last year shows that Langevin owns Facebook holdings valued between $300,000 and $600,000. He said the investment would not stop him from imposing more government oversight on the social media giant.“I am very attentive to the power of social media,” Langevin, who represents Rhode Island’s second district, said Monday in an interview with The Public’s Radio. “I do think that social media companies need to be regulated. I will say irrespective of what I have in financial holdings, I am going to vote on what’s right for the American people and making sure that we have accountability.”

Rhode Island’s first district congressman, David Cicilline, has been vocal in calling for more government oversight of Facebook. Cicilline’s financial disclosure for 2018 does not show any holdings in that company.

“[T]he problem we are hoping to address is the enormous dominance of large technology platforms in the digital marketplace,” Cicilline told NPR last month, during an interview about a broader congressional review of tech companies. “And that results often in anti-competitive behavior that sometimes results in platforms favoring their own products or services or not respecting the privacy interests of consumers.”

In March, Cicilline, the chairman of the House Subcommittee on Antitrust, Commercial and Administrative Law, called for the Federal Trade Commission to investigate Facebook. 

Langevin said he backs the effort to lessen the power of Facebook.

“I think that social media companies – we want to respect the free speech and debate and dialogue – but I think that many of these social media companies have too much power and control about what we see, what they know about us,” he said. “And it’s time our regulators and the Congress have greater scrutiny and appropriate levels of regulation or limits on what social media companies can do with personal and private information and how we can better protect that.”
