Hillary Clinton is now the presumptive nominee of the Dems. I doubt the book would have been written if that were not the case. The author is concerned about the Clinton's reoccupying the WH. As a patriot and someone who is concerned about the future of the Republic, should he hold his tongue or alert the American public to the dangers involved. Patriot or snitch? In the case of the Clintons, I tend to the former.
Remember Unlimited Access : An FBI Agent Inside the Clinton White House by Gary Aldrich?
He did the right thing.
