CBS News Editor-in-Chief Bari Weiss sent a memo to CBS News employees today stating:

“No amount of outrage—whether from activist organizations or the White House—will derail us. We are not out to score points with one side of the political spectrum or to win followers on social media.”

So I have the cover story in next month's TNR.

I interviewed the heads of police groups; immigration defense attorneys, ex-judges and ex-prosecutors; former DOJ and DHS officials, and the former head of Border Patrol.

They're all horrified at what we've seen, and they all fear what's coming.

Remember how EVs could never compete because batteries didn't allow them to go far enough, because they couldn't be charged fast enough, because they were too expensive...?

Funny how innovation works.

The CBS investigation portrays a modern concentration camp, similar to the Soviet GULAG (like CECOT, an acronym): sadistic guards, 24 hour lighting, isolation cells.
Americans once opposed this inhumane system.
The Trump administration sent innocent people there to suffer.

Breaking news: Trump is citing “national security” to halt all active work on offshore wind projects

Five giant energy projects, countless jobs at risk

My story explains how the argument has legal weaknesses and comes from an anti-wind policy doc I reported in January

The administration has already lost once in court wielding the same argument against Revolution Wind.

This comment and reply from the reporter who wrote this story had me vibrating with rage. I’ll call again tomorrow, but I called my congressional rep and Senators immediately to demand something be done

New York | 11h ago It's outrageous that the private companies aren't required to provide adequate protective equipment or insurance for the firefighters who work for them, and that the government doesn't provide those things either. Whether documented or not, these firefighters risk their lives for us. Luis is a hero for his work and the way he lives his life, and he deserves much more help. 226 Recommend Share Hannah Dreier Investigative reporter | 10h ago @Gail Yes, the companies are not required to cover smoke-related cancers in the same way the government does. When another longtime employee of Luis's company got sick with a blood cancer last year, his family launched a fund-raiser that failed to raise enough to cover even a single chemotherapy infusion. The company owner donated $10. This year, the worker switched to palliative care. 66 Recommend Share

But yes, calling fusion "climate tech" does disserve to fusion, and to climate tech.

20% because there's indeed plenty to like about the idea and prospect.

80% because fossil fuel $$$s have turned anything that's scalable today into politically toxic "green"/"alarmist" territory.
