Trump's former campaign manager and White House adviser Steve Bannon is also a former vice president of Cambridge Analytica, but the company said in a statement that none of the Facebook data in question was used as part of its consulting deal with the Trump campaign.
Rep. Mike Conaway, the Texas Republican who led the committee's Russian Federation investigation, said he did not plan to call in Nix or other officials - saying the Russian Federation investigation was over, and it was up to Intelligence Committee Chairman Devin Nunes to decide on future witnesses.

He also suggested making the rival candidate an offer "that's too good to be true" and then putting the video recording on the internet as "evidence of corruption".
