You'd think a person who claims to have "held security clearance, and knowing what I know" would know that there's different levels of security clearance and they're all siloed. There's no BIG BOARD that Elon can just pull up because his companies do space shit and see everything the NSA has hoovered up, Jackie's delinquent taxes and access the Stargate.
His necessarily having a security clearance is a factor of how much irrelevant shit the government classifies, so they have to hand out the clearances like candy or nothing happens.
She also believes that all that stuff classified is shit like the Stargate and cloaking devices and secret impossible missions by Tom Cruise that somehow "our enemies" are ignorant about and could utilize in some way. Meanwhile, the actual US government likes making sure everyone knows just what capabilities it can deploy. And almost all forms of national security information is time sensitive. Declassifying the JFK files or decades of Area 51 projects isn't going to threaten anything but people like Jackie clinging to fantasies about what secrets must exist. As if she could understand them when she can't use a web browser correctly, tries to convince bankruptcy judges that people fabricated her debts and can't even write her own garbage like the Steven Jarvis weirdo.
