I don't think I should penalize people who were doing their duty.

The most important thing we can do is prosecute the offenders, deal with those that have broken the law and committed this crime. And if we can do that then we can begin to deal with this issue and send a signal this is not a problem that we are going to ignore in the United States military.

My experience is that the director of the FBI is particularly important to just how aggressive an investigation will be into an issue. And once you remove James Comey, it creates a vacuum at the top. And the fundamental issue will be whether or not there is support at the highest levels within the FBI to continue to conduct that investigation. That's going to be the question mark.

And thank God our forefathers were smart enough to establish a government of checks and balances to make sure that power cannot be centralized in any one branch of government. And those institutions have proven themselves.
