A couple of things here.
I guess I may have been one of the people that was spied on. I have been very very critical of the crown Prince MBS who ordered the murder of Washington Post reporter an American resident khashoggi. This murder was allegedly greenlit by Trump’s son-in-law Jared Kushner. This is indicative of why the United States of America should not be in bed with Saudi Arabia. they no longer hold oil over our heads so why are we still so close to a regime that murders and tortures there citizenry. One can be stoned by the Saudi regime for being gay. I always thought being stoned was people throwing rocks at you. Nope that’s not it. They dig a pit they put you in it and they slowly lower weights on top of you slowly crushing you to death. This is the government that we are friendly with.
Sure governments, even friendly ones, spy on each other. But using spies within an organization like Twitter to get information on Americans, individual American citizens is beyond the pale.
