I mean, it still is Twitter. That’s the URL that people use to access the site. Tbh I have no idea if Musk actually went through the effort of changing the company name in the business licensing or other company paperwork. Just the logo and header seem to say X. But I agree, I’m getting so annoyed with journalists calling it “the site formerly known as Twitter.” so dumb.
That was actually Major, their younger dog at the time. Champ was their elderly dog who died a couple years ago. They since got a younger pup, Commander, and he too, has been biting staffers, but I don’t know if they revealed which agencies the victims work for. Maybe Commander is copying what his elder brother does, but iirc Major doesn’t live in the White House too often nowadays. He might just have the same intuition.
