It's no secret Caitlyn Jenner is a controversial figure, both at large and within the LGBT community. The reality TV star attended a choral performance over the weekend, and was confronted by a trans activist who couldn't abide Jenner's support of Donald Trump.

At a Trans Chorus of Los Angeles performance on Saturday, Wear Your Voice editor Ashlee Marie Preston stormed up to Jenner, who had help fund the concert. It was only a day after Trump issued guidance on barring trans service members in the U.S. military, and Preston was not having it.

“It’s really fucked up that you are here,” Preston, who filmed the encounter, told Jenner. “Some people may be afraid to confront you for being here, but I am not. You are directly responsible for what has happened with transgender soldiers and the military. I am not afraid to say it to you."

Caitlyn and her entourage tried to defuse the situation, as did chorus co-chair Dena Williams, but Preston persisted.

“You are complicit!" she told Williams. "Taking her money... makes you complicit. It goes against the [chorus'] mission, Dena!"

"We are the ones impacted by the choices that you make," she added. "It’s not okay. It’s not okay,"

Jenner responded by telling Preston "You don’t know me,” to which she retorted “Yes I do! We all do! You are a fraud!” before Jenner walked away and left the auditorium. Preston then turned to Williams and declared, “I thought you were better than that. I’m really disappointed, really disappointed.”

Since then Preston has resigned from the chorus in protest.

While Jenner supported Trump during the campaign, and insisted she could help educate the president on LGBT issues, she has since expressed regret.
