James O’Keefe, the controversial founder of the conservative outlet Project Veritas, was suspended from Twitter on Thursday.

O’Keefe, who boasted more than 900,000 followers, claimed in a post on Facebook that the suspension was linked to his recent reporting on CNN.

In a statement to the Daily Dot, a Twitter spokesperson confirmed that O’Keefe had been permanently suspended for violating rules regarding “platform manipulation and spam.”

“As outlined in our policy on platform manipulation and spam, ‘ you can’t mislead others on Twitter by operating fake accounts,’ and ‘you can’t artificially amplify or disrupt conversations through the use of multiple accounts.’”

Project Veritas recently made headlines after releasing undercover video of a CNN employee discussing the network’s inner workings, alleging it was biased against former President Donald Trump.

The Twitter account for Project Veritas was suspended in February as well for “repeated violations of Twitter’s private information policy.”
