All agencies are independant agencies - meaning simply they have a charter to function per law and the President has limited ability to directly influence there daily operation. I write a check to the department of state to pay for my passport. No different.For those who are quick to favor abolishing the US Postal Service, a simple summary by AI is appropriate:
The USPS is a public, independent entity of the executive branch, not a private corporation. Established in 1970, it functions as a government-business hybrid that is self-funded through postage sales rather than taxpayer money, yet it is mandated to provide universal service to all American addresses.
Why should this have anything to do with abolishing the post office? Either its existential to the operation of the United States (like the Department of State), or it is not (post office). Anything not should go away. If they want to sell it all the better?
