1. Well, it was about ten whole weeks ago.
3. “Operational security is the most important aspect of personnel deployments. The real names, faces, and identities, of personnel involved in special operations or activities, are usually a closely held secret in a combat zone,” Nance said. “Revealing them casually, through an unusual media exposure even if it’s the commander in chief, would prove a propaganda boom if any of this personnel are detained by a hostile government or captured by a terrorist group. There would be no denying who you are and what you do.” --Malcolm Nance. Source: see the link above.
So unless your position is that hostile governments or terrorist groups to not fall under the umbrella of a "national security issue", Tweeting the location and identities of Seal Team Five members definitively fits your criteria of Tweeting national security information "or something of that realm". Well, you were given the chance to Move the Goalposts, but since you did not take the opportunity to do so, what we have here is an event that conclusively meets your criteria for an impeachable offense.
Still, don't see the national security issue.
Too late to Move the Goalposts, Snoopy. Your criteria was for Beloved Leader to have Tweeted national security information "or something of that realm". Point 2 shows that Beloved Leader's did in fact Tweet, Point 3 shows how that Tweet revealed "national security information" "or something of that realm". That's not a matter of speculation. It's on record. And my reply was specifically structured so that your question was answered, your criteria for an impeachable offense met, and that you'd "see" it. You were given the opportunity to Move the Goalposts and you did not take it.
