When McVey got out of the car, he was listening to a handheld scanner and radio that had a remote earpiece, Smith said. Police said he was monitoring local agencies and had formulas for rifle scopes on a note in his cup holder.
Authorities did not say if McVey had a rifle or scope with him.
A rifle scope formula is a set of calculations that helps a shooter adjust for distance from a target. The formulas, which estimate how much a bullet drops after it is fired, are generally in the information packet that comes with a scope purchased for hunting or recreation, said Greg A. Danas, a firearms expert based in Massachusetts.
McVey gave authorities an Ohio driver's license, but a computer check failed to show the number was valid, police said. His hometown of Coshocton is about halfway between Pittsburgh and Columbus, Ohio.
When Officer Kaleb Rice asked him what he was doing, McVey told him he heard the president was in town and wanted to see him.
Rice removed the firearm and took McVey into custody.
The investigation into what McVey was doing with a gun, with formulas for rifle scopes and why his car was equipped with police gear was continuing, Smith said. The Secret Service had no comment on the arrest Sunday, deferring to airport police.
