Where does it say he knew it at the time? It says he’s been briefed but not when the briefing occurred.
The WH now says he wasn’t briefed. I suspect that isn’t true but if so it’s pretty disturbing that information wasn’t presented to him. Trump should be upset at those who failed him on not getting that vital information to him. So far his response has been to attack the media for reporting on it. Why can’t he show the same passion for bounties being placed on our guys that he does for stone replicas of those that betrayed this country?
