A simmering diplomatic stand-off over deportation flights spilled onto social media Sunday, threatening the once close relationship between the US and Colombia and further exposing the anxiety many feel in Latin America towards a second Trump presidency.

Petro’s complaint was that the US government was treating the migrants like criminals by repatriating them in military planes.
