"Actually, I'm not sure we shouldn't be regulated," Zuckerberg said in an interview with CNN that represented some of his first public remarks since the Cambridge Analytica controversy plunged his company into crisis and led to calls for his testimony before Congress.

"I actually think the question is more 'What is the right regulation?' rather than 'Yes or no, should it be regulated?'" Zuckerberg told CNN. 

The Facebook CEO said that "he would love to see" new transparency regulations for political advertisements. Facebook has been criticized for a lack of transparency.

"If you look at how much regulation there is around advertising on TV, in print, you know, it's just not clear why there should be less on the internet," he said.
