Yes, and you cannot rule out that Flynn may have rubbed others the wrong way, others who may have known what was in the report. Other people may have had motives to see him gone from the administration. They may want to protect POTUS from Flynn’s perceived diva recklessness, and they may want his job or level of influence. Again, speculation is just that.
