Sen Diane Feinstein released a report that was not for the general public. While she felt it was the right thing to do, it was her duty to not release what was classified. Still she did and the final result will probably not be good.
Personally, I consider her actions as those of a traitor. Occupying a Senate committee with access to classified materials placed her in a position where she, too, would be the subject of constant investigations. When she found out she was being covertly investigated, she allowed her anger at what she should have known would happen to override the oath she took as a member of the Senate intelligence committee, and used her authority to punish. Releasing classified information allows foreign enemies access to interrogation methods, can lead to retribution, and the ones that suffer will be those that were following orders, or those innocent of nothing but being United States soldiers or citizens.
Feinstein isn't alone with her actions. The Senate Intelligence committee members that voted to allow the release are culpable, also. All should be punished for their actions. They not only failed in performing their duties as committee members, they failed the United States and dishonored those that died defending the greatest nation on Earth.
