Being transparent is also leaking information to Russia and *everyone* else, so I fail to see the difference.
I don't expect our president to be technically capable enough to secure their own data, so they have to rely on experts. And, let's face it, there are precious few experts out there that can secure data 100% when faced with a determined opponent. Government, top-secret projects, companies, etc. have all failed to secure data over time.
When it comes to skills needed to run a country, being able to personally secure their "secret data" is very low on my list, and I would've expected it to be low for most people here.
