President Donald Trump and Colombian President Gustavo Petro defended their views on social media and imposed tariffs on each other’s goods.

Dozens of Colombian illegal migrants arrived home from the United States Tuesday, grateful for an end to a grueling deportation ordeal at the heart of a bitter row between the countries.

President Donald Trump posted threats against Colombia on his social media platform on Sunday after two U.S. military repatriation flights were prevented from landing.
