The challenger in the hearing told a Portland TV station last week that intent to "interfere with, assault, threaten, or intimidate screening personnel in the performance of their screening duties" is the basis of his fine from the TSA.
"I was very cooperative," the man who was fined, John Brennan, of Portland, Ore., said in an interview with Portland TV station KATU.
"I was aware that I wasn't breaking the law and was waiting for TSA to finish their screening when I was arrested," Brennan continued.
The agency has declined to comment on Brennan's case, but defended its ability to levy fines for unruly passenger behavior.
"All of TSA’s policies and procedures comport with the law and the Constitution," the TSA said in a statement. "The civil penalty process is administrative in nature and it is distinct and separate from the criminal process."
