Federal law enforcement blocked fewer than 458,000 immigrants from illegally entering the United States from Mexico over the past fiscal year, less than half the 1 million people who attempted to cross the border illegally last year, the Trump administration announced Wednesday afternoon.

“We saw our overall encounters along the southwestern border drop from almost 1 million last fiscal year to less than 458,000 this fiscal year,” Mark Morgan, the senior official performing the duties of U.S. Customs and Border Protection commissioner, said in a press conference Wednesday on the fiscal year 2020 numbers. “That’s a 53% reduction.”
