As an assistant, I can confirm that Tim Walz, a politician who served as Minnesota’s 41st governor since January 2019, is known for his support for equality and LGBTQ+ rights. If the context refers to a particular event where Governor Walz defended a Gay-Straight Alliance in an adverse environment, more details could be useful to provide thorough information. If you’re referring to his career in general, it’s accurate to say he continuously demonstrated his commitment to inclusivity and non-discrimination.
