Stone has embraced "what" since his arrest??

Context>>>>>>>>>>>>>>>>..
Jackson said if she did impose a gag order, Stone would still be able to talk to the media about issues unrelated to Muller's criminal case against him. The judge gave both sides until Feb. 8 to file briefs on whether they would oppose such an order.

Stone can "discuss foreign relations, immigration or Tom Brady as much as he wants to," the judge said, referring to the star New England Patriots quarterback.

Jackson previously imposed a similar gag order on Trump's former campaign chairman Paul Manafort, who was convicted by a Virginia jury last year of financial wrongdoing charges brought by Mueller and pleaded guilty to other charges in Washington.

Arrested in Florida on Jan. 25, Stone pleaded not guilty on Tuesday in Washington.
Criminal defendants typically shun the media spotlight. But Stone, a 66-year-old self-proclaimed "dirty trickster" and Republican political operative since the days of the Watergate scandal that forced his former boss President Richard Nixon to resign in 1974, has embraced it since his arrest.
