"All the evidence this committee has seen to date suggests that the platform companies - namely Facebook, Instagram, Twitter, Google and YouTube - still have a lot of work to do," Warner said.

The committee has been looking into the issue for months, but concern heightened on Tuesday, when Facebook said it had identified a new coordinated political influence campaign to mislead its users and sow dissension among voters ahead of November's U.S. mid-term elections.

The hearing, which features testimony by experts on technology and cyber security, was scheduled long before Facebook's announcement.

"While it is shocking to think that foreign actors used the social networking and communication mediums that are so central to our lives in an effort to interfere in the core of our democracy, what is even more troubling its that it's still happening today," Senator Richard Burr, the committee's Republican chairman, said in his remarks opening the hearing.

Warner argued that cyber criminals who have been caught "were just the incompetent ones," and said he was concerned that the U.S. government is not well positioned to detect or counter influence operations on social media.

Facebook said on Tuesday it had removed 32 pages and fake accounts from Facebook and Instagram, part of an effort to combat foreign meddling in U.S. elections.

The company stopped short of identifying the source of the misinformation. But members of Congress who had been briefed by Facebook on the matter said the methodology of the influence campaign suggested Russian involvement.
