20 Years of SLA
Tomorrow morning, Science Leadership Academy opens its doors for the 20th time. To say that it has been a heck of a run is purely an understatement. In that time, we've worked with thousands of kids, and we've done all that we can to show the world that an inquiry driven, project based, caring school really can make a difference in the lives of the students and the educators who inhabit it.

AOC connects the dots.
AOC: I want everybody to understand that the cuts to your health care are what’s paying for this. You get screwed over to pay a bunch of thugs in the street that are shooting mothers in the face.

The Hague should make Pete Hegseth’s trial for war crimes a pay-per-view.

Breaking NYT:
The Pentagon used a secret aircraft painted to look like a civilian plane in its first boat attack, according to officials briefed on the matter.
The laws of armed conflict forbid combatants from feigning civilian status.
That is a war crime called "perfidy."

If the #Sixers can stay healthy, they could be really good. At the trade deadline, their only move should be to figure out what contract to shed so they can sign Barlow and Walker to full contracts.
Then, it's about this questions:
* What is Oubre's best role - starter or super-sub w/ Grimes?

This happened in Minneapolis after the Rachel Good murder.
ICE agents are telling us they believe they have the right to kill us.
ICE is Trump's personal paramilitary force, and it needs to be disbanded now.

A woman recording an ICE agent tells him "Shame on you."
The agent responds, "Have you all not learned from the past couple of days?"
"Learned what?" she asks
Then he knocks her phone out of her hand

What will it take for those who have the power and the duty to remove Trump from power lawfully to do so?
How many people have to die?
How many of our rights have to be stripped away?
