(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 
 Question:_ has adopted a similar approach to dealing with those who oppose him.

(CNN) The Marine Corps' fighting ability is undermined by the more than 30,000 active Marines and veterans involved in a private Facebook group being investigated for allegedly posting explicit photos of women in the military without their consent, a former Navy secretary told CNN on Friday. "There's no good excuse," Ray Mabus said on CNN's New Day. "The Marine motto is 'semper fidelis,' always faithful, and what these Marines did was to be unfaithful to their fellow Marines." "Marines look after each other, Marines have each other's back. Look at what the commandant of the Marine Corps said about this, this makes us a less effective fighting force," Mabus said, referring to a video statement posted Tuesday by Gen. Robert Neller.Ray Mabus: "What these Marines did was to be unfaithful to their fellow Marines"Investigation should determine how "Marines United" group developed, he said 
 Question:"These Marines, these veterans, that have participated in this have attacked fellow _, and that is inexcusable in a fighting force, and particularly in the Marines, who are so special."

Militants fighting for the Al Qaeda-affiliated Nusra Front in Syria have released images showing them posing with American anti-tank missiles captured from Western-backed rebels. The terrorists are seen wearing military fatigues as they pose with deadly American-made BGM-71 TOW missiles in a warehouse in Atarib, a town 15 miles west of the city of Aleppo. The showboating images show the masked militants pointing to America logos on cardboard boxes filled with food and weapons, which were seized when the Western-backed moderate rebel group Harakat Hazm recently disbanded and allowed their headquarters to be overrun with jihadis. The emergence of the photographs comes as Nusra Front militants announced they are considering splitting with Al Qaeda in order to create an antonymous terror organisation that can rival the Islamic State's reign of terror in Syria and Iraq.Nusra Front militants seized American weapons and food supplies in SyriaProducts were provided to the Western-backed rebel group Harakat HazmBut the rebels disbanded last week and their warehouses were overrunImages emerged as Nusra Front announced plans to leave Al QaedaRebel group is considering the split to attract Qatari financiers who could help the militants create a terror organisation to rival ISIS
