Riley Gaines received criticisms from radio host and podcaster Brian Shapiro for her advocacy against transgender participation in women's sports and for being a Trump supporter. This stemmed from the former's claim that Democrats have been celebrating right-wing activist Charlie Kirk's assassination, which shook the nation. Riley Gaines has consistently been at the forefront of the movement opposing transgender participation in women's sports. A strong advocate for women's rights, she supported Donald Trump in the presidential election and worked closely with right-wing Republicans such as Charlie Kirk, who was recently assassinated during his address at Utah Valley University.Speaking about it in a recent setting, Gaines revealed that she has been disturbed by the Democrats celebrating the death of 'the most effective debater' of today. Disagreeing with the claim, podcaster Brian Shapiro lambasted Gaines for raking in money from transgender-related campaigns instead of addressing more serious issues. He also took a dig at Gaines's swimming career, noting how she never achieved anything before getting into politics. "...You've made a living attacking transgenders, you've made millions of dollars across the country doing that. You have you've made millions of dollars profiting going across the country. You've made a lot of money and you've made a name for yourself nobody knows who you are as a college swimmer unless you're attacking transgenders now, if you care about children, then why have you not criticized Donald Trump? If you care about children and women, then why have you not gone after Donald Trump for not bringing out the Epstein files? If you care about children, why don't you talk about gun control?"He added:"I'm happy that transgender is out of that volleyball tournament, but there's more important things that we should be talking about, and you've profited off of attacking transgenders with your hatred towards transgender people. Nobody knows who you are as a college swimmer, people know who you are because you go around the country attacking transgenders, Riley that's who you are.."
