What role if any should Congress or the Senate play in situations such as steroids in baseball or spying in the NFL?   

I can somewhat understand trying to curb steroid use at that level because that can have positive effects in limiting steroid use among teens.  However, I still think that there are more pressing issues (ie. better schools, poverty, healthcare to name three) that the legislative branch of government could be working on.  To address Arlen Specter and whoever else is getting involved in the so called "Spygate" I think that it is completely ridiculous and honestly, he should be ashamed of himself for injecting politics where there is absolutely no basis for it.
