Why is this hard to accept?
Are you an idiot? Can you point to the last time some foreigner was given access to American's personal data without any oversight?
It's a joke that any of you assholes are defending this. This does not pass any sniff test.
Stop making excuses.
The president therefore has the authority to access every last secret and every last system within the executive branch. No statute can limit this power. The president also has the authority to delegate (to some extent; only the president can issue EOs, but presumably his officers can recommend EOs to him) these powers to his or her officers.
The titular of the U.S. Digital Service (DOGE) is statutorily not subject to Senate confirmation, though considering how Trump's controversial nominees have sailed through Senate confirmation it's easy to suppose that Musk would also likely be confirmed to head the USDS were it an appointment subject to Senate confirmation. Since the president can appoint someone like Elon Musk to head the USDS, and since the president can delegate his clearance and declassification authority to someone like Elon Musk, his doing so does very much "pass [the] sniff test".
