I admit I cheated and used Google!
As far as I can see only George Bush and Obama had formal state visits hosted by Elizabeth II. So I suppose the question is why is Trump so exceptional to warrant such a visit?
Dwight Eisenhower
John F. Kennedy
Lyndon B. Johnson
Richard Nixon

Ronald Reagan

Trump pledges to “go all out” for a UK-US trade deal if Brexit talks fail

I am sure he does. With the UK in such a weak negotiating position, there is nothing they couldn't force us to take. Chlorinated chicken, reduction in safety standards, access to internal NHS etc.
This kinda reminds me of this clip..
There is currently lots of talk in the media about privatising the NHS and USA insurance and drug companies.
How exactly will they force us?
We have huge trade with the USA already.
Relax - nobody will be forcing you to eat chlorinated chicken..
Although why Chlorinated Chicken is such a big deal for a country that puts Chlorine in its drinking water escapes me..data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7
Obviously it will be devastating if the less well off have access to perfectly safe to eat but cheaper chicken.
I think many people appreciate the safe end to end rearing of chicken vice the US model where hygiene and welfare considerations are secondary because the faeces encrusted meat is just dipped in chlorine at the end of the process.
