OK, I couldn't find it with Google. Everyone inside the Beltway has to use a shorthand name for the various officials. It's the law.

Let me be the first to declare the DC shorthand for the Secretary of the new department (assuming that it passes Congress, with the proposed name).

It's based on the same principle as SecDef for the Secretary of Defense.

There will also be UnderSecHomeSecs.

(By the way, the dental work went OK, for anyone who cares. Light posting this weekend, back to normal on Monday.)
