A few reasons: I was planning on claiming at twilight, preferably after lynching either Red or Ben. However, considering it, I'd like some more time to discuss my info and since there's not really been any clear direction for a lynch, we need to start pushing one way or another. Furthermore, I think we can gain more info today from the reactions from my info if we have more time. Claiming just before deadline isn't an option, and honestly, I think claiming in Twilight or tomorrow risks me being lynched by a combo of Scum and annoyed Town.
Why hold your claim to your chest at all if you were going to claim it before the night kill? ---
