Scientist at centre of Facebook scandal didn't think data would be used to target voters

The man who helped gather Facebook users' information for Cambridge Analytica claims that he didn't think it'd be used to target voters.

Data scientist Aleksandr Kogan, who also goes by the surname of Spectre, told CNN's Anderson Cooper on Tuesday that he was "heavily siloed" from knowing about the UK data firm's clients and funders, who are linked to the 2016 Trump election campaign.

"I found out about Donald Trump just like everybody else, through the news," Kogan told the program.
