Hao Lee was enjoying the afternoon last week fishing with his 2-year-old son along the Sacramento River — until he heard someone yelling by his truck parked 50 yards away along the highway hugging the water.

What was the person yelling? Well, Lee is a supporter of Republican presidential nominee Donald Trump, KTXL-TV reported, and he had a pair of Trump stickers affixed to his truck's rear bumper.

"I heard somebody yelling out 'F Trump,'" Lee told the station.

But he said that wasn't the worst of it: "After that I heard [glass] breaking, I called 911, couple minutes later I saw smoke."

Fearing for his son's safety, Lee didn't venture toward his truck until the commotion subsided — and by then flames were shooting out of his truck's windows, KTXL reported.

"I didn't think anybody would do this kind of stuff over a bumper sticker," he told the station. "It's not right."

Sacramento City Fire Department arson investigators processed the scene for clues, KTXL said, and the truck was towed away — a total loss.

Meanwhile Lee had to figure out some way to explain to his son what happened.

"He loves trucks," he told the station, "so I'll tell him I'll get him a new truck."
