United States officials said Friday that the number of migrants arriving at the southwestern border last month was the largest in years, a sign that the surge this year may extend into the hotter summer months when numbers typically start dropping.

President Biden came under renewed pressure on immigration Friday as the authorities said the largest number of migrants in years arrived at the border with Mexico last month and a federal judge in Texas raised legal questions about an Obama-era program that protects young immigrants from deportation.
