EXCLUSIVE — U.S. air marshals are planning to stage an open rebellion against the Biden administration over a plan that would strip 99% of commercial flights from federal protection as people take to the skies during the busiest time of the year for air travel.

Dozens of federal air marshals have agreed to refuse a Biden administration order that they leave their assignments and go to the southern border, where they will drive, feed, and care for illegal immigrants due to a shortage of Border Patrol agents.
