"You fake news you dumb piece of shit", Stone wrote [sic], according to The Hollywood Reporter, one of the first outlets to report on the ban.
Stone wrote on Facebook that Twitter had notified him that the suspension would last only a few hours.
"This is a unusual way to do business and part and parcel of the systematic effort by the tech left to censor and silence conservative voices", Stone said on Sunday in an e-mail to Politico, warning that "the battle against free speech has just begun" and saying he planned to take legal action against Twitter.
For now, though, Stone joins his pal and fellow alt-right booster Milo Yiannopoulos on Twitter's lifetime blacklist. As others on Twitter have pointed out, the President receives far more clear-cut threats on a daily basis from left-leaning commentators, with no action taken by Twitter.
Stone, who helped Trump win the election, told Politico on Sunday he had made a decision to bring legal action against Twitter, although it was unclear what that action would be. When it comes to removing tweets, the company added that one of the considerations is whether a tweet is of public interest or not.
Stone also told Politico that he, his family, and even his dog have received death threats on Twitter. Stone was briefly an adviser to the Trump campaign, and has been personally tied to activities that come under Mueller's purview, including the hack of the Democratic National Committee.
The feds haven't released the charges against Manafort, who ran Trump's campaign as he rose from outsider to frontrunner in the GOP primary, though he's expected to face tax fraud charges. Several years ago, Stone got a tattoo of Nixon on his back.
