In March, a Nazi flag was hung on the north Morgan Hill overpass in where supporters of President Donald Trump had gathered for a political demonstration.
The CHP said the crash was triggered when a Ford pickup truck traveling north on Highway 101 in Sunnyvale struck the center divider and came to a stop, blocking some northbound lanes. Other cars then hit the pickup and also stopped in the northbound lanes.
The officer, who was not identified, reported that he was not injured when his personal vehicle was struck at least one time by gun fire on Highway 101 near Route 85.
