Inside the Mexico City stadium where migrants have been regrouping and recovering since Monday after more than three weeks on the road, few are aware of the debate awaiting them in the US. In the functional mini-city that’s sprung up — replete with clowns, yoga instructors, a volleyball court, mariachis, and a food truck corner — there’s not much in the way of talk about US politics…

It remains unclear how long the caravan, which at one point numbered around 7,200, will remain in the capital.

For now, the migrants are getting their blistered feet treated by doctors and their sore calves massaged by volunteers. Every inch of the massive sports complex where the caravan is resting is taken up by tents, clusters of people playing cards, local vendors selling cigarettes and peanuts, and portable power stations for migrants to charge their cellphones.
