After meeting with Mark Zuckerberg on Monday, a key Democratic senator said Americans risk losing their right to privacy without more regulation of social media platforms.

Sen. Bill Nelson, D-Fla., met with the Facebook CEO for more than an hour on Monday ahead of Zuckerberg's Capitol Hill testimony Tuesday and Wednesday. Nelson, ranking member of the Senate Commerce Committee, called for more oversight of social media platforms to protect user data.
