The PM and Foreign Secretary should be condemning this illegal strike and breach of international human rights law.
After years of arming a genocide and worshipping the “special relationship”, Trump now believes he can act with impunity.

It's January 2026. Welcome to the UNC system, where you can soon expect an army of Nick Shirleys to show up in classrooms and harass faculty and students thanks to their dimwitted misunderstanding of publicly searchable syllabi. Or as Peter Hans puts it, this is how we rebuild public trust!

Good review on what’s going on at NIH.
“Polling consistently shows strong majorities favor federal investment in health research. The dismantling we’re witnessing is instead the result of a political moment in which a minority viewpoint holds disproportionate power.”

"Don’t you like it, Hamas whore?"
Per the Freedom Flotilla Coalition, that's what Israeli guards said to Flotilla member Vincenzo Fullone as they horrifically sexually assaulted him.
He was one of at least 3 members of the Flotilla who were subjected to sexual violence by Israeli authorities.

Your ability to take paid time off to recover from illness or injury or childbirth shouldn't depend on where you live.

I only took the GRE and the SAT…am I required to sit for the ACT? LSAT? MCAT????
Which links to this proposed Act, which says "...requiring all parts of a state university system to publish every higher-education standardized test score (SAT, ACT, CRT, GRE, LSAT, MCAT, etc.) of every faculty member..." and every applicant.
So it's super dumb, but not "SAT but not GRE."

Zero actionable response. All talk, no action. This is all everyday Americans can do.

The Epstein Files Transparency Act required the DOJ to publish ALL records, documents, communications, and investigative material in its possession, while withholding ONLY the private information of victims and survivors. What they released on Friday simply does not comply with the law. 1/2

More than 100 immigration judges have been fired nationwide since Trump took office. 21 in San Francisco alone, many without explanation.
Why? Because these judges provided due process under US law.
The Trump admin doesn’t want hearings or fairness.

Ran out of words so it isn't as clear as it should have been. Basically the argument is people on the "out" who have very bad experiences don't return and "in" people have a good experience so keep coming back. Such a situation would give you the same good numbers as a "fair" system.
