What about the Trump hotel in DC? It’s been very recently refurbished and he could set things up the way he wants. He would have more control over security etc than the WH which might be compromised because more people are likely to know all the security details at the WH from past administrations.
But, I’m sure that the WH is a virtual bunker and there’s probably an internal route to a real bunker that could sustain a pretty big hit.
Sorry, wrong post.
