Good morning. The #migrantcaravan has now been on the march for three weeks. Here’s a quick update from last night, when I spoke to several members after Trump warned he wanted soldiers to shoot them if the migrants threw rocks. News of Trump’s comments had reached the caravan by Thursday night in Matias Romero Avendano, where the migrants were camped in a soggy sports field on the edge of town, a few miles from where Mexican families celebrated the Day of the Dead in the town cemetery.
