NEW YORK — Roger J. Stone Jr., an ally of President Trump and a self-proclaimed political “dirty trickster,’’ has been kicked off Twitter.

In a series of tweets on Friday, Stone insulted several CNN news anchors and contributors. The messages appeared to be in response to reports that a federal grand jury had approved charges in the investigation into the Trump campaign’s possible connections to Russian operatives.

Stone’s posts were littered with expletives. He said Don Lemon, the host of “CNN Tonight,’’ “must be confronted, humiliated, mocked and punished.’’ He said Bill Kristol, a conservative pundit was “packing on the pounds’’ and he used the hashtag #porky.

He used an expletive to describe the political pundit Ana Navarro and wrote that Jake Tapper, who hosts “The Lead’’ on CNN, “must be held accountable for his lies and very severely punished.’’

Then his Twitter account was suspended. It was unclear whether that would be permanent.

Stone told The Wrap he would sue Twitter. “The battle for free speech has just begun,’’ he said.
