The National Border Patrol Council (NBPC) tore into the end of Title 42 — the pandemic-era law allowing certain migrants to be booted — as Border Patrol Chief Raul Ortiz confirmed that "upwards of 60,000 migrants" are "staging in and around the immediate border area."

"This is by far the worst sustained disaster that any BP agent, active or retired, has ever seen at our border," the service's official union tweeted just before Title 42 ended at midnight.

"And one man is responsible for every single bit of it, with the worst still to come," the NBPC wrote alongside a photo of a smiling Biden.
