What is the speaker's opinion on Bossert's statement and Trump's influence on his followers?
["No one would perceive that as a threat, I hope they don't," Bossert said, referring to the tweet.]
Why would you hope they don't if you don't believe anyone would perceive that as a threat?  Hope doesn't exist for events that are certain to happen, ie. no one says I hope the sun rises tomorrow if they know it is going to happen.
How can this guy be an "advisor" to Homeland Security and say videos on social media and believe "no one would perceive that as a threat?"  ISIS release videos on social media to inspire terrorist acts all over the world and Trump has more than his fair share of believers in even the most incomprehensible conspiracy theory.  For example the shooter in Pizzagate.
What's even worse is that Trump spouts that this crap is "MODERN DAY PRESIDENTIAL" and his followers will slurp it up with their $20, made in China, MAGA™ plastic spoon.
