And of course ICE in Maine is retribution for Gov. Mills's in-person clash with Trump in February over his anti-trans crusade. They tried to rip major USDA funding away from the University of Maine in March, but Sen. Collins was able to reverse that. What will she say/do about the stormtroopers?
If anyone was still pretending this isn’t just about excluding trans kids from public life, the Trump administration just opened a Title IX investigation into a Maine school district because a trans student is on a *co-ed* cheerleading squad.

The U.S. Department of Education announced a slew of Title IX-related investigations this week that include 2 school districts in Maine.

I think this was the way to let @wrigleyfield.bsky.social know you're available to guest lecture for folks in MN. So list your topics and I'm sure she'll add our posts to her thread!

Finally, a note to the many professors in my networks: One other specific, small thing you can do from outside of Minneapolis is reach out to colleagues who are heavily affected (because of their own or their family's risk, or because they're very busy protecting neighbors) and offer a guest lecture

Trump administration rolls back $2 billion mental health, addiction grant cuts
Sweeping cuts to mental health and addiction programs worth more than $2 billion are being reversed. After a political backlash from Republicans and Democrats, the grant money will be restored.

BREAKING — Mayor of Lewiston, Maine posts on FB that ICE is coming to the city imminently. This confirms my reporting the agency is planning a surge in the city and state generally.
Lewiston is home to a large Somali-American population, which made up 4.6% of the population as of the 2020 census.

It’s too much. And I don’t (currently) have stormtroopers occupying or preparing to occupy my town. But still, it’s too much.

EPA hasn't "stopped monetizing the health benefits of ozone and particulate matter." They've repudiated any attempt at risk assessment for those pollutants. There's a difference, and it makes a difference.

Funny you should post that this morning. Our neighbors are Swiss and use real candles on their xmas tree. They light them only 4-5 times a season. But this morning, having been awoken by a sick kiddo, we stumbled downstairs only to see through the window that the candles were lit. 🎄🕯️🕯️🕯️🕯️

In economics this is known as a Maralago improvement.
Sen. Kevin Cramer: "Maybe the point should be if you're the attorney for Jay Powell and you want to avoid an indictment, how about you go to Jeanine Pirro and say, 'I'll make a deal. I'll step down today if you drop the investigation today.' To me, that would be a win win for everybody."
