Senator Lindsey Graham wants a 9/11-type commission to explore ways to curb the influence of foreign government/entities on US social media sites.
His call comes as the House intelligence panel released thousands of social media accounts placed by Russian accounts to influence the US election and its aftermath.
The South Carolina Republican said "manipulation of social media sites by terrorist organizations and foreign governments is one of the greatest threats to American democracy and a significant threat to our national security."
Graham said the problem is to determine whether any legislation can be constructed that is consistent with our Constitution and values.
A Commission would include experts in technology and national security.
