Congressional Hearing, American signatures - nothing to do with the ISU. The ISU is an International organization, so the whackadooodles in congress have no say over what they do. They'd like to think they have that power, but they do not. I'm not even sure they can force the USFSA to do anything? They can suggest, they can not recognize (threaten) but that's about it. Think of how they fuss about steroids in sports. It's a big waste of time.
And why does the link only mention the women's figure skating (which is really ladies, or did that change?)
What can the US do? Figure skating crosses state boundaries. The skates you wear are likely made in another state, competitors travel interstate to compete & test . . . . .so under the Commerce Clause ...Congress has broad powers to regulate it because figure skating is part of our national economy. The USFSA can probably be regulated by laws passed by Congress to make competitions more fair. Competitors are spending thousands, in not millions, to compete. Think of baseball, Lance Armstrong, and NFL head injuries....congressional inquiries. Private sports groups have to follow rules too. (Lance Armstrong, if I remember right, was taking extra EES/erythropoitien, a natural hormone that everyone produces in their kidneys that tells their bones to make more hemoglobin/red blood cells. More hemoglobin, more oxygen, better performance.) So, if a figure skating competition is patently unfair, it will discourage others from joining it, it affects commerce, and Congress has an interest.
Plus, if hearings can distract the population from more important things, Congress will do it.
Those 2+ million votes on President Obama's change.org page is a cause of concern to me.
