(CNN) Though many individuals likely contributed to the President's decision to fire FBI Director James Comey, one notable one may have been Roger Stone, a 64-year-old close friend of Donald Trump and central figure in the FBI investigation into Trump campaign ties to Russia. In the middle of the Watergate scandal, Stone, who engaged in dirty tricks during Richard Nixon's 1972 campaign, was discovered to have hired a Republican operative to infiltrate the George McGovern campaign and was subsequently fired from his job. After the President's resignation, Stone remained an ardent Nixon apologist and loyalist. He even had the man's face tattooed on his back and devoted his life to ruthless, anything-goes politics (or political consulting, as you may know it). Stone's motto was and continues to be: "Admit nothing, deny everything, launch counterattack." And anyone who has watched Trump closely over the years would think it was his personal slogan, too.Michael D'Antonio: Roger Stone has undoubtedly influenced President Trump's decision to fire James ComeyAs an old friend and political adviser, Stone has taught Trump be ruthless -- particularly when protecting himself from attackTherefore Comey, who was leading the investigation into Trump campaign ties to Russia, had to be taken out, writes D'Antonio
