It's being widely reported today that Sinema has registered as an Independent. Although she hasn't said explicitly about caucusing with Democrats, Politico reports that she intends to get committee assignments from Democrats, which almost certainly means caucusing with the Dems. She also almost certainly voted in the Dem caucus leadership election a few days ago (since there was no reporting that she didn't).
