Documents released from a Cambridge Analytica senior official disclose that Donald Trump’s 2016 campaign for president illegally coordinated with one of the SuperPACs supporting Trump’s run for office, the Associated Press reports.

According to a complaint filed by the nonpartisan watchdog group Campaign Legal Center, the Trump campaign, then led by Kellyanne Conway, coordinated with the Make America Number 1 SuperPAC to post advertising on social media using data Cambridge Analytica had improperly obtained from Facebook. 

Conway had led an earlier version of the SuperPAC when she supported the candidacy of Texas republican Senator Ted Cruz. Make America Number 1 was financed by conservative billionaire Robert Mercer, who also founded, owned and managed Cambridge Analytica with Trump campaign advisor Steve Bannon.  Bannon and Conway were awarded jobs in the Trump Administration after the election.

The allegations outline a scheme in which Cambridge Analytica acted as a middleman for information between the campaign and the SuperPAC.  Cambridge Analytica would with the campaign to develop ads and messaging attacking Democratic presidential candidate Hillary Clinton and then work with the SuperPAC to run the ads on social media platforms.

Campaigns are barred from coordinating in any way with independent SuperPACs, and such coordination must be reported to the Federal Election Committee as an in-kind contribution.  None of the organizations involved made any such notification.
