The diplomatic drama that began over the weekend provided clues on how Trump would deal with countries standing in the way of his immigration policies.

Colombian President Gustavo Petro announced that Colombia was suspending permission for previously authorized U.S. deportation flights to land in Colombia. Ostensibly driving Petro’s action were concerns that Colombian nationals were not being treated with respect during the deportation process because they were being transported by military aircraft.

While Colombia has avoided tariffs that would have a devastating effect on its economy, visa restrictions that were issued on Sunday by the US State Department are still in place.
