It made me so sad and angry to see these scientific budget cuts. We're eating our intellectual seed corn. NASA has to operate on timelines longer than a presidential term, this feel unrecoverable.

Congressional Republicans have surrendered their power to the president they are constitutionally obligated to oversee.
It is a startling abdication, rivaled only by the Trump’s lies to voters about what his foreign policy would be once he took office.

Whether it’s Donald Trump demanding Greenland from Denmark or Barack Obama asking for Dijon mustard from a hotdog vendor, both presidents made some highly unusual requests.

In case any of my friends in Europe or the UK need to hear it: all of this is fucking bullshit. All of it. I am a USian and I am incredibly embarrassed by all of it. Stephen Miller in particular can eat a fucking dick. I am 100% in favor of the rule of law as are all of the USians I respect. Fuuuck.
