New York Times bestselling author Milo Yiannopoulos is joining longtime advisor to President Donald Trump and Republican strategist Roger Stone in an anti-trust lawsuit against Twitter.

In July 2016, Twitter permanently suspended his account after he wrote a negative review of the all-female Ghostbusters movie.

Stone also had his account permanently suspended in October 2017 after posting several expletive-laced tweets. Both contend they did not violate Twitter’s terms of service and were unfairly targeted.

In a statement about Yiannopoulos joining the lawsuit, Roger Stone said:

“We continue to explore a broad lawsuit challenging Twitter’s censorship and the hypocrisy of their rules for online conduct which seem to be disproportionately levied against conservative voices in an obvious attempt to silence us. Verified tweeters call for my murder online every day, but Twitter doesn’t ban them.

“We believe it is time to expose their manipulation of algorithms, ‘shadowbanning’ and other online techniques used to limit our reach. It’s time for Twitter to be regulated like a public utility or perish. I am heartened that my friend Milo is prepared to join our legal action along with other conservatives who have been gagged by the Twitter censors.”

In a Jan. 11 statement about the anti-trust case, Milo said:

“I am Patient Zero of the Twitter war against conservatives and libertarians. The company declared war on free speech when it banned me in July 2016. At the time, I appreciated the free press. But I have come to realize that Twitter’s recklessness and bias toward conservatives and free thinkers represents a threat to free speech and democracy, such is Twitter’s monopolistic grip on journalistic discourse.

“Footage released this week by investigative journalists at Project Veritas reveal a defiantly biased company whose hateful and divisive political attitudes are robbing libertarians and conservative journalists and media personalities of the right to freely express their opinions in the press.

“The biggest tech debate of the next decade is whether technology companies, in particular, social networks, should be regulated as public utilities. It is becoming increasingly clear, given their rampant abuses, that they should. And Twitter is the worst offender of them all.”

Milo will be discussing details of the case in a live episode of his new show, The Milo Show, on Dangerous.com, at 2:30 p.m. ET. Thursday.
