Every single DOGE access to any level of protected government data is a security breach. Not snark. None of them have clearances.
If they're accessing data that requires clearances, they have the required clearances. That's mandatory, and no one is going to show them anything without them.
My guess, based on the fact you use terms like "protected government data" is that you don't even know enough about this topic to make up words about it.
There is no "forcing access". It simply doesn't work that way.
If the President clears them, they are cleared. That's perfectly legal. The President is the federal government's OCA.
