Mostly to be a pedantic devil's advocate here, I'm going to argue with something you're not saying. I've heard a _lot_ of people argue that the visit is _proof_ of corruption. You're just pointing out the possibility and I'm hoping to head off a bad path.

Anyway, if a company is being declared the source of a multi-state outbreak, that company _should_ be talking to the WH. And it's possible that some of those discussions would present evidence that _should_ result in a retraction.

For example, during heartbleed my grand-boss was in on calls with the WH (I don't work on openssl, at the time I worked on a product that _used_ openssl a couple of layers down). AIUI, official guidance changed because of those calls.

If we want to find proof of corruption, this is a place to start looking, not a place to stop.
