James Clapper isn’t exactly my favorite appointee of the Obama era. But I still perk up when someone of his background and experience talks like this, as reported by Julian Borger at The Guardian. After Donald Trump’s incredibly discreditable performance in Phoenix Tuesday night, Clapper, former director of national intelligence for a little more than six years under Obama, challenged Trump’s “fitness to be in this office,” and said it’s “pretty damn scary” that he has access to the nation’s nuclear codes: Once a president has verified his identity with a code kept constantly on his person or nearby, the military chain of command has no power to block his launch orders.
