I use my local library from my phone with the Libby app. I don't know if this benefits them as much as going there in person does. I did go there to get a library card though, you need one to sign up in the app.
But they have a great catalog of ebooks that I can borrow from, I've read the bulk of The Dresden Files that way recently and I'm about to finish it if the last two books ever come off reservation.
This isn't about needing clarification though. Like you said, clarification is not necessary. This move is about being able to wave this amendment around in front of everyone, and publicly force Republicans to agree on its meaning, ahead of Trump ignoring it.
I don't see this as being completely a bad move but I am not a legal expert. I also won't call it a good move, but it will force the hand of the Republicans who wish to ignore this law into publicly stating as much. This would have been a lot more effective earlier though I think.
