Couple reasons why this whole thing today was just a propaganda photo-op...
1- The reason that church was picked by government officials in PR is because the leaders are Americans from the mainland, who are Evangelical Christians, and part of the very, very small group of Trump supporters in the island. Basically, the shit in the church was propped and staged to benefit Trump, Jennifer Gonzalez (who has an aid who called the Obamas "monkey" all the time on social media) and Ricky Rosello, who is a puppet.
2- Trump and his minions landed in Base Muniz in Carolina, which is only 15 minutes away from Loiza, Rio Grande and other towns in the southeast of PR who were completely destroyed by Maria. Instead, he was taken to Guaynabo, which has some damage, but not as much as other areas, and that is 30-40 minutes away from the base.
This was all set up for Trump to look good and for him to continue with his narrative that everything is fine in PR, federal help is doing good work, and that the mayor of San Juan is lying.
