The unscreened bathrooms contained only a single sheet to cover their lower bodies.

Detained by US immigration authorities for eight days, the workers and their families expressed shock, describing human rights violations and absurdities they could not have imagined as ordinary Koreans living in 2025.

The government continues to cancel grants at both NIH and NSF to censor science it doesn't like.
We're tracking terminations to organize and advocate. Please report your terminated grants:

Not sure who needs to hear this, but any govt official who violates someone's constitutional rights -- and is acting outside the scope of their lawful authority -- can be PERSONALLY liable in a civil suit.
ICE officers. Cabinet members. White House staffers. Even the president.
Observe that the one that complied and the one that didn't comply are treated exactly the same way.

A MORAL CRISIS
βThe rule of law is being trampled. Innocent people are being disappeared. Court orders are being ignored.
If you claim to love this countryβif you believe in the Constitution, due process, order, and justiceβthis must be your line in the sand.β
Take 3 minutes. This is important.
I had been doubtful that we were going to have a "this is the crisis moment" with Trump, as opposed to "everything about this is a destructive catastrophe."
But the Abrego Garcia case is the crisis moment.
