James Woolsey, President Clinton’s former CIA director, said he is advising Donald Trump on national security matters because the Republican presidential candidate won’t “blab” or “go yakking” about state secrets, and because he thinks Hillary Clinton would spend too much.

Woolsey said during a Monday interview on CNN that Trump “seems willing to keep a secret and not to blab everything to the public and our opponents when he comes up with something about national security that ought to be kept quiet.”
