About SS agent stroke and paraglider: paraglider guy made his appearance on friday night when Trump arrived his golf resort. The secret service agent died saturday night, a day later. If he was exposed to some poison, it took exactly 1 day to affect him. That might narrow it down.
I strongly think the cabal was testing his defences and found a weakness. They can't allow these types of things to happen again. If you're not willing to effectively eliminate all threats againts POTUS, expect much more attacks like this in near future.
They now know all it takes to get close to POTUS is to send some "innocent greenpeace or equilevant protester" near him with some made up excuse and execute your actual plan when everyone is paying attention to that protester.
