I mean what does vetting even mean anymore? Our President is a convicted felon, our head of HHS thinks bad humors cause illness and vaccines cause Autism, our head of Education is dismantling her own organization with the approved sign off of the Supreme Court, of whom a solid percentage are accused sex offenders, and I could keep going with the utter circus our Government is currently.

Not only are qualifications not required they are apparently actively discouraged in favor of nepotism and connections.

The guy who heads up the Defense department was (drunkenly?) texting out secret plans to a journalist.

And the DNI regularly repeats Russian propaganda meant for Russian internal media... If it seems odd to anyone that our president seemed genuinely surprised that Putin was "tapping him along" consider who advises him. And our two most recent presidents both liked keeping classified documents in insecure locations. The situation is ridiculous and everyone just seems to shrug. I don't know if our overlords got way worse at this or they just stopped caring. We can't even get a high quality supervillain to rule us anymore.

I knew a guy with clearance that cashed out 100% of his retirement to fly to Moscow to meet a sex worker he'd be involved with online. It never affected his clearance.

Dude would run his mouth about stuff he shouldn't tell people under normal circumstances. There's no way he didn't tell the sex worker secret stuff.

There’s no single overarching federal requirement when it comes to citizenship etc, but I would’ve assumed that ITAR requirements at the very least would’ve made this work US citizen on US soil only.

Permanent residents are US Persons for ITAR purposes

Which is a rule that needs to be changed.
