Donald Trump came one vote away from getting the Supreme Court to say that the 14th Amendment does not guarantee birthright citizenship for the children of undocumented and temporary immigrants, a view held only by fringe far-right nativists until VERY recently. This is shocking. I am stunned.

Really enjoyed the time with James at Risky Business. Between his James Kettle interview and mine: the models we have today can already do remarkable work; if you take the time to codify your expertise into scaffolding. And what that looks like with IronCurtain, and on what businesses need to do.
