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.

President Trump frequently demonstrates his disdain for journalists. He expresses his admiration for authoritarians almost as often. Tuesday showed how intertwined those two instincts really are.

Donald Trump could have just kept his mouth shut about Jamal Khashoggi.
But to smear a dead journalist, while sitting with the person accused of orchestrating his murder is just vile.
Every time this administration hits rock bottom, a trap door seems to open.
Cretin behavior.

Increase in productivity since 1979: 87%
Increase in hourly pay since 1979: 32%
Just so happens that ~25% of workers were unionized in 1979. Today? 10%.
As unions declined, the super-rich have taken a larger share of wealth generated by labor. We must build back union power.

All of the times I’ve wondered what Putin had on Trump, and now we find out Jeffrey Epstein was talking to Putin’s ambassador about Trump.
Jeffrey Epstein claimed he gave Russians insight into Trump
Newly released emails show the late convicted sex offender’s extensive network of foreign contacts, whom he corresponded with about Trump’s policy decisions.

Really cant understand how badly the Dems messaged this fold. The easy out was to say "we never expected Trump would illegally starve children and when SCOTUS stepped in to illegally help him we couldn't put kids at risk."

Either a) Schumer couldn’t hold his caucus together or b) he orchestrated this and wants plausible deniability.
Neither scenario is good for him or the Democrats.
They just gave away the most important piece of Democratic legislation of the 21st Century.

But there really isn’t a better explanation for why Johnson won’t convene the House.

Speaker Johnson is officially keeping the House in recess again next week. This will be the eighth consecutive week the House has been out of session. The chamber hasn't met since Sept. 19. Adelita Grijalva, who was elected on Sept. 23, has not been sworn in.

I have lost the ability to tell the difference between when it’s Trump or when it’s AI.
Trump says we are preparing to invade Nigeria. Apparently that’s what voters said they wanted in the exit polls. Trump: “We’re going to do things to Nigeria that Nigeria’s not gonna be happy about. Guns-a-blazin!”
