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.

So the House is going to vote TOMORROW on the DHS funding bill that includes funding for ICE.
There's a real chance we can get Dems to vote NO on any bill with ICE funding to sink it.
Once it goes to the Senate we likely lose this chance.
24 hours. Go.

In case the algorithm hasn’t delivered this to you yet, Donald Trump wrote a truly insane message to the Norwegian, Prime Minister, and here it is. The entire Republican Party is still lockstep with this guy.

The laws of armed conflict forbid combatants from feigning civilian status.

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.
