A dumb question for one of you to answer.

3. Technically...

A President is immune from prosecution for any acts performed in office as functions of his duties. According to what the Supreme Court ruled, he can be charged with things that don't qualify as part of his job. Of course, the definition of those limits will change quite a bit once a Democrat is in office. Currently, President Trump can claim anything he does is part of his job, and SCOTUS will back him up.

So, if someone appointed by the President orders an illegal act, it probably depends whether or not those orders are advancing the President's agenda, although the stated position of SCOTUS is that the immunity is limited to the office-holder himself.
