The committee said Wylie provided it with documents including a services agreement between AIQ and SCL Elections, Cambridge Analytica’s parent company, dated September 2014.Reuters was unable to independently verify the authenticity of the documents made public by the committee.AIQ did not respond to Reuters’ request for comment after Tuesday’s committee hearing, but in an earlier statement said it had never entered into a contract with Cambridge Analytica and had never been part of the firm.Cambridge Analytica has said it did not share the Facebook profile data with AggregateIQ, did not use it in the campaign to elect Donald Trump, and has deleted the data.
