Before I start on this story, I'd like to address one point that has come up time and time again - While I know that James Mattis (otherwise known as Mad Dog Mattis), Trumps former Secretary of Defense, is thought to have been fired by Trump by many. That isn't true Mattis offered his resignation to Trump and then all Trump did was expedite his departure. Maybe that is a technical firing, but the guy was resigning at first. I don't think this should have anything to do with his criticism of the President though.
Most of Mattis' statement revolved around the fact that he was accusing Trump of not even trying to unite the country together, and was happier with dividing the country against one another during a time of protest. He didn't agree with the way that Trump is using non peaceful means to breakup peaceful protesters. All in all, he pretty much said that Trumps leadership isn't mature, and that it is important for us AS A COUNTRY to unite back together as one or we're going to have issues. Here's some quotes from his speech / statement:
“Donald Trump is the first president in my lifetime who does not try to unite the American people—does not even pretend to try. Instead, he tries to divide us,” Mattis writes. “We are witnessing the consequences of three years of this deliberate effort. We are witnessing the consequences of three years without mature leadership. We can unite without him, drawing on the strengths inherent in our civil society. This will not be easy, as the past few days have shown, but we owe it to our fellow citizens; to past generations that bled to defend our promise; and to our children.”
“When I joined the military, some 50 years ago,” he writes, “I swore an oath to support and defend the Constitution. Never did I dream that troops taking that same oath would be ordered under any circumstance to violate the Constitutional rights of their fellow citizens—much less to provide a bizarre photo op for the elected commander-in-chief, with military leadership standing alongside.”
Lisa Murkowski offered her support of Mattis' criticism and hinted at the fact that she may not vote for Trump come Novemeber. Crazy, crazy times.
