Senator Sanders has questions about Twamp's Russian ties

See this video for the details. He asks:

1. Did Twamp campaign collude with Russia?
2. Is Twamp susceptible to blackmail?
3. Are we jeopardizing our alliances?
4. How far does the relationship go between Twamp and Russia?
5. What's the real reason Twamp won't release his tax returns?

Since Twampler refuses to answer these questions Congress must take its Constitutional duty seriously to get answers. We already know Republicans won't do this because they only pay lip service to the law when it suits their insatiable lust for power.
