The commondreams article says "endorsement of taxes on ultra-wealthy individuals and large corporations" - your linked article says she's raising the corporate tax rate not even up to what it was before Trump. So, sure, I guess that technically counts as the "large corporations" part, but it doesn't meet the "ultra-wealthy individuals" language or the "billionaires tax" claim in the headlines.
I love that she says she wants to raise it somewhat. I love that she wants to give tax breaks to working class people. I don't love that this makes it out to be something it's not.
Honestly, it's surprising if he's the first, but at least it's not (yet) something journalists can expect!
Almost like the British were the terrorists the whole time.
