This guy is so full of **** I'm surprised you don't just see it actually tumbling out of his mouth.
For those who don't know about Daraprim, the side effects are pretty minimal. It has basic things like maybe a rash, or maybe gastrointestinal side effects, and maybe head ache or light headedness.
The idea that a drug that works with minimal side effects is a "70 year old drug that we can do better" is asinine. There's more side effects to pretty much any other drug.
