Fumigating the White House

Assuming the creature doesn't bring about the nuclear destruction of the planet, the White House will have to be totally overhauled for the next occupant.

Donald Trump has turned one of our greatest national sites into an infected sewer. The job of disinfecting every square inch of the White House will be immense.

Perhaps the most efficient solution is to burn it to the ground and rebuild it from scratch. So much history would be lost. But is there a better/safer alternative?

And once the White House has been purified or rebuilt, I guess we're going to have to figure out how to purify and rebuild all the other things he infected. You know. Things like America.
