@6G@mastodon.social but that's not how Congress works.
Firstly, the rules of the Senate don't give any senator, including McConnell, the power to unilaterally stop anything. At any point the rest of the chamber could overrule him if they wanted to.
The fingerpointing at McConnell was always a way of scapegoating that allowed senators to escape accountability for their inaction.
Well, that and a way for reporters to publish clickbait headlines.
But the idea of Congress blocking legislation overall? No. If legislation isn't compelling then it's not Congress blocking it, but Congress simply saying it's not something they're interested in passing.
