Republicans, what would your reaction be if Biden gave the same access to Soros as Trump gave to Musk?
Uncleared, unchecked people with no security clearance have full access to all private information of every American. They have the ability to install any software on Treasury servers, including backdoors for undetectable future access. And there is absolutely no oversight.
EDIT for clarification: One of the most important things in the American political system is oversight and transparency. You can trust people, but they are still human, meaning they are flawed. Even if you think that Trump and Musk are flawless (they are definitely absolutely not), there are people working with Musk whom you don’t know at all, and apparently, even attempting to know their names is considered a crime.
