The Scientists Groveling to Trump Are Kidding Themselves The government has pulled back from massive cuts to the NIH, but itโ€™s still destroying scientific research. So why are some groups appeasing the president?

Thanking Donald Trump for signing the budget bill, which spared NIH from the knife was unseemly and unnecessary. In fact, the destruction of American science is gathering steam under this administration and appeasement won't help. My latest for @thenation.com. www.thenation.com/article/soci...

This Is America, Just Not the America You Knew Two white people were killed by ICE in Minneapolis and suddenly White America is outraged.

America is outraged after ICE killed two white people in Minneapolis.

I understand why folks are feeling afraid and angry right now. But I need you to understand something just as clearly: this is what Black America has been living with for generations.
