(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.

Washington (CNN) Donald Trump on Wednesday asserted that the Democratic National Committee hadn't been hacked at all -- and in fact conjured the story itself -- after the party's research on Trump was purportedly sent to journalists by a hacker. "This is all information that has been out there for many years. Much of it is false and/or entirely inaccurate," Trump said in a statement. "We believe it was the DNC that did the 'hacking' as a way to distract from the many issues facing their deeply flawed candidate and failed party leader.
