There has been some talk that an assassination was attempted on Trump and that was the cause of the secrete service agent's death. I would imagine if that scenario was accurate it would affect Trump on multiple levels causing Anger, seeming Off in recent interviews, concern for the family of the deceased agent, concerned for his family, etc. Could also be why Q has gone silent as they got wind of the plot and had to address the threat and tighten the security around Potus. Everyone so inclined should say a prayer for everyone's safety and guidance while they navigate these next few months. I can't imagine the stress they are all under.
