A former Google insider claiming the company created algorithms to hide its political bias within artificial intelligence platforms – in effect targeting particular words, phrases and contexts to promote, alter, reference or manipulate perceptions of Internet content – delivered roughly 950 pages of documents to the Department of Justice’s Antitrust division Friday.

The former Google insider, who has already spoken in to the nonprofit organization Project Veritas, met with SaraACarter.com on several occasions last week. He was interviewed in silhouette, to conceal his identity, in group’s latest film, which they say exposes bias inside the social media platform.

Several weeks prior, the insider mailed a laptop to the DOJ containing the same information delivered on Friday, they said. The former insider is choosing to remain anonymous until Project Verita’s James O’Keefe reveals his identity tomorrow (Wednesday).
