USA Today:

A political action committee run by President Trump's incoming national security adviser relied on research from Cambridge Analytica, the voter profiling firm that Facebook has accused of unauthorized use of its user data. 

The John Bolton Super PAC, founded by the former ambassador to the United Nations, paid Cambridge Analytica more than $811,000 for "survey research" during the 2016 campaign, according to Federal Election Commission filings. Overall, the PAC paid the British firm nearly $1.2 million over two years, according to The New York Times. 

Bolton's PAC was one Cambridge Analytica's first customers when it hired the data firm in August 2014, reportedly for the specific purpose of creating psychological profiles on voters based on the Facebook data harvested from millions of users without their knowledge.
