Roger Stone Roger Jason StoneOur Constitution is under attack by Attorney General William Barr Justice IG investigating Stone sentencing: report Romney says Trump's protest tweets 'clearly intended to further inflame racial tensions' MORE's Twitter account has been suspended.

The suspension appeared to come after the former adviser to President Trump's election campaign went on a tirade on the social media site Friday, taking aim at CNN, particularly "CNN Tonight" anchor Don Lemon and "The Lead" anchor Jake Tapper.

In the profanity-laced tirade, Stone called certain employees of the network "human excrement" and accused them of spreading lies, according to copies of the tweets posted online by Mediaite.

The series of tweets came after CNN reported that a grand jury had approved the first charges in special counsel Robert Mueller's investigation into Russian interference in the 2016 election.

A spokesperson for Twitter declined to comment about individual accounts, but pointed The Hill to the social media site's policy on abusive behavior, which prohibits "behavior that crosses the line into abuse, including behavior that harasses, intimidates, or uses fear to silence another user’s voice."

It's not the first time Stone's had his Twitter account suspended. It was temporarily taken down in April after he made threatening remarks to Laura Keiter, the communications director for Media Matters, a progressive media watchdog group.

His account was suspended before that in March for apparently violating the social media site's rules.
