President Trump is making his first visit to the U.K. as president, meeting with Prime Minister Theresa May at her country estate and having tea with the Queen at Windsor Castle.
The flip side: Trump is extremely unpopular in the U.K., and his visit has whipped up tremendous controversy. He's largely avoiding London while in the U.K., but the mass demonstrations there have loomed over the visit.
