Cambridge Analytica whistleblower Christopher Wylie on Tuesday told British Parliament that his company worked in India and that he "believe" Congress was a client. "I believe their (Cambridge Analytica) client was Congress but I know that they have done all kinds of projects. I don't remember a national project but I know regionally. India's so big that one state can be as big as Britain," he said as part of his deposition.
