Bloomberg has reported there was a "direct collaboration" between employees of Facebook and Google and conservative nonprofit Secure America Now and ad firm Harris Media.
Facebook also reportedly worked with the far-right Alternative for Germany party, which is also a Harris Media client, to target voters with anti-immigration ads during this year’s election.
During the U.S. presidential campaign, one ad was a mock tourism film entitled Book Your Trip to the Islamic State of France.
The ads reportedly ran in Nevada and North Carolina in the final weeks of the election.
Sources told Bloomberg that sales teams at Facebook and Google worked closely with Secure America Now to improve its multimillion dollar ad campaigns.
Bloomberg reported that Google eventually pulled some of the ads after they violated its policies, whereas Facebook went as far as using Secure America Now’s ads to A/B test at scale a new video format.
