Bannon, Mercer and Nix 'were warned' during campaign that Cambridge Analytica's practices may violate US law: whistleblower
Cambridge Analytica whistleblower Christopher Wylie

Cambridge Analytica whistleblower Christopher Wylie on Thursday alleged that during the 2016 presidential campaign, Donald Trump’s former chief campaign strategist Steve Bannon, billionaire Republican donor Rebekah Mercer and Cambridge Analytica CEO Alexander Nix were warned that the company's actions may violate American law.

MSNBC host Ari Melber asked Wylie if he had knowledge of warnings sent to Cambridge Analytica or its officers during his time at the company.

“Yep, absolutely,” Wylie told Melber. “Rudy Giuliani’s law firm actually sent us a memo to Steve Bannon, Rebekah Mercer and Alexander Nix that actually outlined the fact that, in the United States, you can’t run campaigns with foreign citizens who are not permanent residents.”

“The company was warned that Alexander Nix should recuse himself of substantive management duties in the company as CEO and they are also warned that the company shouldn’t be sending foreign citizens to go and run American campaigns,” Wylie said. “But that was completely disregarded.”

Melber asked Wylie to confirm that he was alleging “Giuliani’s law firm warned the people you named during the campaign, and your view is they ignored those warning?”

“They did, they completely disregarded it,” Wylie replied. "And I have the memo to prove it.”
