Nearly 100 minutes before former President Donald J. Trump took the stage in Butler, Pa., a local countersniper who was part of the broader security detail let his colleagues know his shift was ending.
He exited the second floor of a warehouse that overlooked the campaign rally site, leaving two other countersnipers behind.
Outside, the officer noticed a young man with long stringy hair sitting on a picnic table near the warehouse.
So at 4:26 p.m., he texted his colleagues about the man, who was outside the fenced area of the Butler Fair Show grounds where Mr. Trump was to appear.
He said that the person would have seen him come out with his rifle and “knows you guys are up there.”
Persons:
Donald J, Trump, ”
