Hi, I'm Rush Holt. I'm a member of Congress, a candidate for Senate, and an astrophysicist. AMA!
You might know me as the congressman who beat IBM's supercomputer Watson in Jeopardy. A few weeks ago, reddit helped focus attention on my new legislation to repeal the PATRIOT Act and the FISA Amendments Act and end the surveillance state (http://www.reddit.com/r/technology/comments/1iisbr/nj_congressman_rush_holt_is_attempting_to_repeal/) -- thanks to those who chimed in.
I'm also an astrophysicist and would be the only scientist in the Senate. I've been sharing a series of "Geek Out" videos (http://www.rushholt.com/video) drawing on my scientific background to make an evidence-based case for progressive ideas. At that link is a new 15-second video regarding the NSA, just released now for reddit.
Ask me anything!
Update (1:20): I have to go now, I will check in later this afternoon and try to answer a few more questions. Thanks for letting me join you.
Update (4:20): I'm back to answer questions for a few minutes more.
Update (4:50): And signing off. Thanks again: http://i.imgur.com/bCBlMZP.jpg
