Children stopped at border likely hit record-high in July

The American Civil Liberties Union and other advocacy groups say they are ending settlement talks with the Biden administration over a demand to lift a pandemic-related ban on families seeking asylum in the United States. The breakdown comes three days after two nongovernmental organizations said they were halting work with the administration to identify particularly vulnerable migrants stuck in Mexico for exemptions to Title 42, named for a 1944 public health law. The administration has denied many families and nearly all single adults an opportunity to seek asylum on grounds of preventing spread of the coronavirus. (AP Photo/Eugene Garcia, File)

SAN DIEGO — The number of children traveling alone who were picked up at the Mexican border by U.S. immigration authorities likely hit an all-time high in July, and the number of people who came in families likely reached its second-highest total on record, a U.S. official said Monday, citing preliminary government figures.
