MEXICO CITY (AP) — A top U.S. delegation is meeting with Mexico’s president about a surge of migrants reaching the U.S. southwestern border. Mexican President Andrés Manuel López Obrador says he is willing to help limit the surge, as he has done before. But he says he wants to see progress in U.S. relations with Cuba and Venezuela, which are two of the top sources of migrants. He would also like to see more development aid for the region. The U.S. team is headed by U.S. Secretary of State Antony Blinken.
