Biden and Mexico leader discuss migration

US President-elect Joe Biden told Mexico's president Saturday he was committed to addressing the root causes of poor Latino migrants crossing the border into America.

Outgoing President Donald Trump made tightening the southern frontier against what he called the free and dangerous flow of people entering the US from Mexico and Central America a key pillar of his US-centric policy on immigration, including his fitful plan to build a border wall.

Biden spoke Saturday with President Andres Manuel Lopez Obrador and emphasized "the need to reinvigorate US-Mexico cooperation to ensure safe and orderly migration," the Biden transition team said in a statement.
