Facebook's chief executive, Mark Zuckerberg, testified in the first session of privacy-focused hearings on Capitol Hill. When asked why Facebook had not informed US FTC about Cambridge Analytica data harvesting, Zuckerberg said Cambridge Analytica had told them that 'they weren't using the data and deleted it – we considered it a closed case'. He also said that Cambridge Analytica wasn't banned from Facebook at the time because, 'as of the time we learnt about their activity in 2015, they weren't an advertiser, so we actually had nothing to ban'.
