I don't trust Breitbart to do factual reporting (based on their extensive history of false reporting) and this report from May 2016 shows nothing about a caravan in November 2018. Even if it was related, this report says nothing about open borders. As I understand the migrants are looking for asylum, which is an extensive process with a low success rate. How is that "open borders"?
