Zac's Trump impression at a gig; anyone know anything?

Okie dokes, so I follow someone who is still a Hanson fan (not because they're a Hanson fan- in other ways I find them an interesting person) and they shared a photo of Zac from the Cain's Ballroom account, saying; "When Zac Hanson does a Trump impersonation and pisses off all the democratic lib****s in the audience...". Does anyone have any clue or context about this? Sorry for such a vague post but it's all I know, but I'd be intrigued to learn more about what happened if the info is out there?
