Mamdani rescinded every executive order issued by Eric Adams after Adams's indictment, but still the "New York Times" is focusing exclusively on two of those orders that had to do with Israel.
There is someone singling out Israel here. And it isn't Zohran Mamdani.

Same with scientists. Each "fun" generative AI thing shared makes me a little less confident in the quality of your research.
Deleted a repost of a thread.
Looking closer, the person is comfortable sharing AI images & video. Was the thread also AI? Was it accurate?
I’d rather not take the chance and share it.
Journalists, keep this in mind. “Fun” AI videos & images undercut your credibility.

Y ahora en serio, si queréis una base de datos de nombres molones, consultad a cualquier persona trans que tengáis en vuestra vida. Los hemos revisado todos. Todos los que existen. Los hemos revisado, sopesado y probado docenas de veces. NADIE sabe más de nombres que nosotres.

Spray paint a plane and they'll detain you without trial and call you a terrorist.
Kidnap a foreign head of state - and Keir Starmer will make it clear we've played no part in it but will wait for the scheduled press conference in a few hours before potentially condemning it

I notice how Meloni isn't even mentioned, despite Italy being about the same size as UK and France: perhaps because she is, formally, more rightwing than the others.
In practice, I see little difference.

European weakness on full display by these horribly contorted responses from Merz, Macron and Starmer - neither condoning nor condemning US actions in Venezuela
Such weakness only risks making the Europeans more vulnerable (ie Greenland)
