For a moment on Sunday, the government of Colombia’s Gustavo Petro looked like it might be the first in Latin America to take a meaningful stand against President Donald Trump’s mass-deportation plans.

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.

Donald Trump’s mass deportation plan hit a brief stumbling block on January 26 when Colombia’s president, Gustavo Petro, refused to allow two US flights carrying deported Colombian migrants to land. Petro’s complaint was that the US government was treating the migrants like criminals by repatriating them in military planes.

Two Colombian air force planes carrying deportees from the United States arrived in Bogota on Tuesday, the government said, paving the way for U.S. President Donald Trump's administration to lift visa restrictions and other measures on Colombian citizens.
