A delegation of top U.S. officials is expected to visit Mexico soon as negotiations over how to enforce immigration rules at the two countries’ shared border continue on Capitol Hill. President Joe Biden spoke with Mexican President Andrés Manuel López Obrador on Thursday and agreed that additional border enforcement was needed so the crossings can be reopened, according to White House national security spokesman John Kirby. Biden asked Secretary of State Antony Blinken, Homeland Security Secretary Alejandro Mayorkas and White House homeland security adviser Liz Sherwood-Randall to travel to Mexico in the coming days to meet with López Obrador and his team to discuss further actions that can be taken to address the challenge.
