Stop Elon Musk and his associates from messing with the US government systems?

Elon Musk and his associates are getting more than read only access to a number of our vital US government computer systems like in Treasury and Dept of Education. These people shouldn't have anything more than read only access, because they have not been adequately vetted to have the appropriate clearances to this information. I encourage you to call your sentators and representatives to stop them from having access to our private information.
