As a former Air Force B-1 pilot, and now as a member of the House Permanent Select Committee on Intelligence, I have handled some of our country’s most sensitive information. I recently had the opportunity to read 29 emails that were contained on Hillary Clinton’s private server. Having done so, it is clear to me these emails contain extraordinarily sensitive information. They do reveal classified sources. They do reveal classified methods. Worst of all, they also reveal sensitive human assets.

It’s important to understand what this means. The official definition of TOP SECRET is that the information is so sensitive that its disclosure could be expected to cause “exceptionally grave damage to the national security.”
