IDK, but at this point its all pretty arbitrary however they do it since it seems to be spreading in some parts of the USA pretty well already. I guess less travel, whether it's EU, UK or even domestic, is better, but where from doesn't really matter as much anymore so Trump picked some for political purpose.
Because Boris is UK-Trump? (said only semi-seriously, I don't follow UK politics close enough to know for sure how good the comparison is)
I suspect it's a matter of the "special relationship" the US and UK have had for decades; Trump doesn't want to be seen as the one throwing our UK friends under the bus, especially with the promises he made during the lead-up to and implementation of Brexit.
> His speech said all travel from Europe would be suspended but a presidential proclamation later said it would only apply to anyone who had been in the EU's Schengen border-free area in the 14 days before their arrival in the US.
You been in (Schengen) Europe the last 14 days? And not being an exempted person (eg US citizen/resident)? Then you are not going.
You could probably go to London, stay there 14 days and then go on. Problem is, in 2 weeks time, travel will likely be farther restricted.
