I think this could be a benefit to Mr. Trump with the Hispanic community. Especially since he and Peña Nieto have managed to get along well and agree on many things. From what I've read there has been none of the negativity Trump literally spews on the stump.
I think it is good to get along with one's neighbors as much as possible. Perhaps Trump received new insights about the issue. Personally, I think rather than building a wall that would cost the earth and take years to build, it would make more sense to use that money (Mexico's money according to Trump) to create jobs and more opportunity in Mexico.
I understand that many people want to embrace refugees and others who only want to come here as most of our own ancestors did, to make a better life for themselves and their families. The problem is that the entire world population, or even half of it, will not fit on the land area of the U.S. At least not comfortably or conveniently. Not even safely.
So to me it makes more sense to build up those countries that lack opportunities for their people to do well. Build them up so that their people will want to stay and do well where they already are and where they are familiar.
To me, it even makes more sense for the U.S. to invest in other countries rather than moving hundreds of thousands of their population to this country. It is simply not feasible for all humans to live here in this one country, and it seems idiotic that opportunity cannot be created in other countries as well as it is here.
As other countries are built up and become fiscally stable, they will start creating their own jobs and opportunities keeping their population at home (except for touristing) and raising their incomes to levels equivalent to our own, thus making it less desirable for our companies to go to other countries for lower wage workers.
When the standard of living is equivalent in all other countries it will no longer make sense to move our jobs out of this country because it will cost essentially the same, or possibly even more, to employ people in a thriving economy elsewhere.
Sorry to get off subject. To wrap it up, I've read that Trump's acceptance of Neito's invitation has angered some people, but I think overall he has improved his image to the voters. Especially Hispanic voters who before wouldn't give him the time of day. Now, I think they may consider voting for him -- so long as he doesn't undo his progress by mouthing off as usual.
