The party that was compiling unconstitutional registries and databases illegally with big tech is now concerned with personal data being exposed from a read only file of accounts payable of the fed.
Not particularly thrilled with training Mexican anti-cartel troops as there's a long history of this not working out.
Mexican leadership is inherently compromised. I think you need to just hit the shit out of the cartels directly and teach them not to mess with anything/anyone that has to do with the US.
That plus the border and money laundering would do 95% of the job.
