Mike Pompeo's tweet: "One week from today, I will be stepping aside as Secretary of State and this account will be archived. Be sure to follow me @mikepompeo. Go do it now."

What did he mean about stepping aside. Could mean just out of the way, but this implies that he is going to stay in the government just in a different role. He could have said "step down" and this would be vacating him his post overall. He could have said his term was up as SOS and that he will be out.

The word "aside" literally translates to:

a remark or passage in a play that is intended to be heard by the audience but unheard by the other characters in the play.

This is exactly what is going on with everything. The audience is supposed to know something is different, but the characters keep playing as normal - none the wiser.
