In July 2024, Selzler was among Democratic National Committee members who opposed plans to conduct the party's presidential nomination through an expedited virtual roll call before the 2024 Democratic National Convention. ABC News reported that Selzler urged the party to retain the presidential nomination and roll call at the convention, expressing concern that an accelerated virtual vote could create the perception the party was attempting to silence debate or prematurely conclude the nomination process.
In August 2026, the District 44 Democratic-NPL Executive Committee appointed Selzler to the North Dakota Senate to complete the term of Josh Boschee after Boschee resigned following his election as mayor of Fargo. Selzler assumed office on August 5, 2026.
Weight loss and fitness Selzler has publicly discussed his experience with obesity and weight loss. Valley News Live reported in February 2026 that his weight had reached 652 pounds and that he subsequently lost more than 350 pounds over approximately three and a half years. He initially increased his physical activity through walking and later added GLP-1 medication and resistance training.
In February 2026, The New York Times profiled Selzler in an article examining how GLP-1 medications can affect people's relationships with exercise. Selzler began using Wegovy in 2023 after experiencing significant limitations in his mobility. As he lost weight, he progressively increased his physical activity, eventually walking and hiking regularly and strength training four days per week. The Times reported that Selzler's relationship with exercise changed substantially during his weight loss, and that he began enjoying physical activity for the first time.
Selzler subsequently became a certified personal trainer, certified nutrition coach, and certified wellness coach through the National Academy of Sports Medicine. NASM reported in 2026 that he had lost more than 370 pounds and had begun working with others on weight management, fitness, and behavior change.
