Conservative Abelardo de la Espriella was sworn in as Colombia's president on Friday, vowing to crack down on armed drug gangs and tighten ties with the United States. The flamboyant former lawyer and ally of Donald Trump brings a sharp turn to the right for the Andean nation, promising to bomb jungle cocaine labs, build “mega prisons” and shrink the size of the state. He also pledged to wage war on drug-running guerrillas. Vice-President Jose Manuel Restrepo joined De la Espriella in the ceremony, and the two cheered, embraced and performed their campaign's characteristic military salute. De la Espriella's inauguration marks a new era of close relations with Washington, a shift that signals a tougher line on security and a smaller government at home.
