Whether trump can legally create a whole new government department by executive order is up for debate, but he did it and hired these people into roles within it. By my math they have 0 right to hide from the expected scrutiny of any other public official.
What government organization in the US federal government hides the names of their leaders? Can you name one? Even our security agencies make those names publicly known.
I don't see what that has to do with anything in the discussion so far?
It looks like you can't believe that there are bad arguments for good causes; and instead want to keep arguing that the cause is good, and thus all arguments must be good?
