Sen. Marco Rubio, R-Fla., does not believe Facebook has fully disclosed to the Senate Intelligence Committee the full extent of what the social media giant does with information from its vast roster of users.
In an interview with NBC News' "Meet The Press" aired Sunday, Rubio, a member of the panel, said he was "disturbed" by news Facebook might have known in the summer of 2016 that profiles of users were in the hands of political consulting firm Cambridge Analytica without the users' knowledge.
"I'm disturbed by that," he said, adding "I'm disturbed by the fact that Facebook has created filters to help the Chinese government censor. And they're begging to get back into China. There's a lot I'm disturbed about these things."
Pressed on whether Facebook has been forthcoming about everything it has done with its users, Rubio responded, "No I don't."
"And I think we've learned that the hard way," he said. "Every time that we've spoken to them it's kind of rolled out as more coming out. Look, these companies have grown very fast within the span of less than 10 years they've gone from being a novel idea to a major corporation.
"And I'm not sure if the sort of institutional knowledge about the responsibilities both legal and ethical that come with that have kept pace with their growth."
He said the growth spurt and "so much good press" has made the social media company "get up high on themselves that they start to think that perhaps they're above sort of the rules that apply to everybody else."
