But in terms of timing, this, combined with the fossil record of E/SE Asia, is convincing that Sahul was settled long before much of Eurasia.

I went to Minneapolis to see what it means when ICE occupies a city. And I left with one unmistakable realization: ICE is not broken. It is working exactly as President Donald Trump wants it to.
It cannot be reformed or retrained. It must be abolished.

I know all eyes are on Minneapolis, but there's a fast-approaching nightmare in Springfield, Ohio.
Trump is revoking protected status for tens of thousands of Haitians living there on Feb. 3.
Reportedly, on Feb. 4, 1000 ICE agents are arriving to remove this population. Ethnic cleansing.

I hope you know that you and Nate Silver enabled this by arguing that Abolish ICE was an unviable position and that Democrats needed to adopt conservative immigration policies.

Abolish ICE is not enough.
Stern words for Greg Bovino or Kristi Noem is not enough.
We need prosecutions and trials.
Anything short of this position fails to address the gravity of this moment.
