Since the president suspended his controversial family separation policy in June, illegal border crossings have skyrocketed. According to unpublished Border Patrol data, there were more than 16,000 family members arrested in September — an 80 percent increase over July.
A Border Patrol official who was not authorized to speak publicly tells CBS News that agents at the border "are swamped," with more and more large groups crossing together. The official said on Sept. 20, Border Patrol encountered 275 adults and children. On Oct. 2, that number was 164 adults and children.
On "60 Minutes," correspondent Lesley Stahl asked the president if he would return to his family separation policy.
"Frankly, when you don't do separation, when you allow the parents to stay together, OK, when you allow that, then what happens is people are going to pour into our country," he said.
"So are you going to go back to that?" Stahl asked.
"Well, we're looking at a lot of things," he said.
These caravans happen from time to time. The migrants travel in groups for safety. In April, several hundred made it to the U.S. border near San Diego, and a limited number were allowed to apply for asylum in the U.S.
