Mattis and Trump certainly are a far cry from the ineptitude of BOTH previous administrations. And they're the two who want more proof. There's one thing we've learned for sure since President Trump took office......the swamp is deeper and dirtier than anyone could've imagined and its tentacles extend far beyond DC. NO ONE can be trusted. (I even have some doubts about certain young, unschooled in world affairs and self-centered Trump family members). I hope Mattis and Trump carefully vet those sources and their background.
Would President Trump ever have given up his wonderful life in an attempt to save the US if he know how bad it is? I can't think of any President who has given up more in a sincere effort to save the nation.
