“Thank you @iheartradio Wango Tango for having me & thank you to everyone who joined me in orange,” wrote the Canadian star, while sharing some photos from his performance.

A day before taking to the stage, Mendes shared a post encouraging his followers to “tell your senators to take action on gun safety now” by texting “BOLD” to 644-33. 

“Today is National Gun Violence Awareness day,” he wrote in the caption. “Tomorrow, I’m performing at @iheartradio Wango Tango, and I’ll be in Orange. If you’re coming or you’re tuning in, join me & #WearOrange 🧡.”
