I groan whenever Hillary is brought up but she lost to Trump behind a lot of the Russian games and bs we're still seeing to this day come out. She absolutely has a say in the matter she was directly affected by it.
Also OT but what other senior Dems are you looking to hear from on the matter? Most of them are old as dirt, dead, tainted, not allowed to talk about it ie Obama, Biden, the top intel people with clearances at the time(if they were even dems), and or are currently speaking out about it.
