I worked 4 years in the USAF with a Top Secret Crypto clearance and handled TS material and communications.
Wow...was that before or after the invention of the cell phone and internet? Cause ya see, the NSA is capable of some pretty high tech surveillance but not at the behest of the President. The President doesn't really have that power...steps were taken after Nixon to make to very difficult for surveillance to be done for political purposes vs national security purposes–which you seem to conflate...
Trump found about the surveillance after the election. But the surveillance had been going on for at least 6 months before the election.
What surveillance? Flynn was picked up as incidental collection of a foreign agent intercept...the NSA wasn't eavesdropping on Flynn, they were eavesdropping on Sergey Kislyak who happened to talk to Flynn and lied about what was talked about–the full story of which we still don't know.
So, what other surveillance? Are you talking about the FISA warrant to surveil Carter Page? That was the FBI not the NSA who surveilled Page after it was found he was dealing with actual known Russian FSB agents who were trying to recruit him. The FBI FISA warrant went back to July 2016 as it relates to the Russian collusion investigation but indications are Page had been under surveillance since 2014.
So, who else was under surveillance and by whom?
The whole reason that the FBI was alerted to the Russian interference in the election was because of foreign intelligence agencies waring their American counterparts that people who had connections to Trump were having meetings and conversations with Russian agents. We don't know exactly who but the assumption is the both British and German intelligence agencies while engaging in surveillance of Russians were finding the Russians either talking to or talking about people with Trump connections. I also wouldn't be surprised that Israeli's Mossad might have caught wind of things as well. But we don't know this because none to the foreign or domestic agencies are talking about it.
So, who else? Perhaps Paul Manafort because he was already under investigation for money laundering using Cyprus banks that are known entities used by both the Russian government and the Russian mob.
Who else? Donny Jr? Ivanka? Jared Kushner? Kushner might be a target because of his family's involvement in sketchy real estate deals. Trump himself?
All of that is crap...
Some Americans got caught up with foreign surveillance...Susan Rice as National Security Advisor to Obama did her job and asked for the unmasking of certain names because of national security implications. Pretty sure that's how Flynn got caught and that was AFTER the election dooode.
Carter Page? Well, he met with Russian agents who tried to recruit him and the FBI got a FISA warrant to put him under surveillance. Electronic surveillance? Prolly both his phones and internet/email. Could Trump have been incidentally caught up with Carter Page surveillance? I dunno...maybe...
But here's the thing you have to ask yourself...if Obama did what you claim he did and had Trump and his campaign under surveillance, do you believe the entire conspiracy to help Hillary and hurt Trump was so inept that Trump won inspire of the conspiracy?
Or is this all just a pipe dream to explain away Trump's paranoid delusions and to claim that all of this post election bullshyte is simply a feeble attempt by the democrats to deny legitimacy of Trump's presidency? I meant, that's what Trump says...but even Trump's own interagency agencies say Russia interfered and the DOJ and the FBI/ say there's no evidence of Trump being eavesdropped on.
You keep spewing forth unfounded allegations and irrational claims that are delusional. And whether or not you had Top Secret clearance decades ago bears little on this argument.
If you have sources to back up your claim that the surveillance had been going on for at least 6 months before the election. Prove it...otherwise I say
