Why is congress involved with steroids?

Answer 1

Because they THINK they have the authority to get involved. The thing you have to understand about Congress is that, particularly when Democrats are in charge, they THINK they should have control over everything that happens in the entire world. So they IGNORE constitutional restraints on their actions and TRY to legislate everything they can get their arrogant, power-hungry hands on. Or at least hold HEARINGS about it. They are, unfortunately, successful for the most part at these power grabs because the President, the Supreme Court, and most importantly the PEOPLE, do not reign them in.
