Mexican President Andrés Manuel López Obrador will host President Biden for dinner during a welcome ceremony Monday night in Mexico City. The event will occur ahead of a regional summit on Tuesday that will include Canadian Prime Minister Justin Trudeau. Migration, climate change, trade and manufacturing are among the major topics on the agenda. Biden arrived late Sunday in Mexico after visiting the Texas city of El Paso for a firsthand look at the influx of thousands of undocumented migrants crossing the border with Mexico.
