Days after issuing threats of military action against Colombia, US President Donald Trump said he had invited Colombian President Gustavo Petro to the White House following what was described as a cordial phone conversation. Petro, who had strongly condemned the US operation targeting Nicolás Maduro, later appeared at a rally in Bogotá framed around defending national sovereignty in the face of Trump’s threats, where he said he had called for renewed dialogue between the two countries.
