Immigration and Customs Enforcement denied the agency helped charter several flights for illegal immigrants, even as a Republican lawmaker seeks answers from the Department of Homeland Security.

The agency denied involvement in organizing flights that landed at the Wilkes-Barre Scranton International Airport on Dec. 11, 17, and 25, according to the Times Tribune. A spokeswoman from ICE suggested the flights may have been chartered by another agency and denied they belonged to them.
