In a twitter video, O' Keefe explained, "in paving the way to establish citizen journalism, I have been defamed, arrested, raided, and ultimately removed from the organization I spent so much time developing credibility of. I always knew they would try to ruin the reputations of those who exposed them, the pharma giants, the three-letter government agencies, and those who I thought I could trust."

"But in response, we are going to build an army of investigators and exposers. They have awakened sleeping giants. I'm back."

O'Keefe revealed in February this year that he was kicked out of Project Veritas, despite being a founder of the organization.
