ATLANTA (AP) — Federal immigration officers have been seen at an airport in Atlanta after President Donald Trump said he’d deploy agents to supplement the Transportation Security Administration during a government shutdown that has caused long lines at security checkpoints across the country. On Monday morning, a handful of federal agents were noticed by The Associated Press near busy lines at Hartsfield–Jackson Atlanta International Airport. Federal agents are typically present at international airports, where Customs and Border Protection officers screen arriving travelers, and Homeland Security Investigations agents handle criminal cases tied to smuggling, trafficking, and fraud. However, their visibility at TSA security checkpoints is unusual, as this role is typically handled by transportation security officers. President Trump announced on Sunday that he would order federal immigration agents to airports to assist with security.
