A man who stripped naked at an airport security checkpoint in Portland, Oregon, earlier this week said his act was a form of protest against airport screening measures. John Brennan told the Associated Press he was being “nude, but not lewd” and cast his actions as political speech. Brennan was arrested and initially charged with disorderly conduct and indecent exposure after stripping naked at Portland International Airport. Brennan says he decided to strip when he was pulled aside after he had gone through a metal detector and a patdown. His actions come amid mounting criticism over airport security measures, including concerns over the health impacts of full-body scanners used in many airports.
