Can We Mandate Swimming in Public Schools?

In the US the government has wide control over public schools. They require equal educational opportunities for pupils of different races and ethnicities, the length of the school year, and of course vaccinations, but what about mandating swimming? Why isn't this vital life-skill a requirement in public schools nationwide? We'll speak to Shawn Slevin, activist, swim coach, and the founder of Swim Strong, about how her organization has put forth two bills in the New York house and senate to have learning to swim as a required part of the pubic schools curriculum.
