On Oct. 18, Judicial Watch, a conservative group that spends much of its time on endeavors like lawsuits to retrieve documents from Hillary Clinton’s time as secretary of state and investigations of alleged voter fraud, published a piece on the Guatemalan president’s statement, warning: “Why should Americans care about this? A caravan of Central American migrants is making its way north.”
Three days later, on Oct. 21, the group’s president, Tom Fitton, appeared on “Fox & Friends” to discuss its report and said that Guatemala had become “a way station” for terrorists.
The next morning, at 8:37, Mr. Trump tweeted about the caravan, “Criminals and unknown Middle Easterners are mixed in,” a claim he later walked back because he said he did not have evidence. The next day, however, a Department of Homeland Security official tweeted that citizens from all over the world, including the Middle East, were traveling with the caravan.
