Just going to mark my own pet theory here.

Often construction work is associated with "mysterious" fires. In this case a fire at the White House would be the perfect pretext to move the White House to Mar-a-lago.

I'm going with "accidental" fire that occurs during construction that renders the White House uninhabitable. That would see Mar-a-lago become home of the presidency. That's my pet theory.

I'd be going for Mumps given it's a recognised cause for severe pain in the testicles.

Sounds about right.
