The question that has to be asked is why was the WH meeting held? Is it SOP or Law that congressional members have to be informed of impending military action?
Looking at the participants, some of those (e.g., Schiff) have been called out publicly as leakers. In Schiff's case, it was requested by GOP members that he be removed from his committee chairmanship.
IMO, any classified information regarding military operations wouldn't be given to him. If the meeting was held because it had to be, then any information would not be accurate/usable. Drawing from that, it would best be used to feed suspected leakers a barium meal, and that is what I think happened.
I believe reports in the NYT that Trump ordered attacks, then withdrew them came before any official statement from Trump himself. Not sure about that, but if that was the case ,it points to a barium meal. MH trying to talk shit in subsequent tweets points to that as well.
