Leo hinted that he (they) may file a QW...but of course that hasn't happened yet and may never happen. Aside from that, it appears that no other attorney or group has publicly shown an interest.
Mario Appuzzo has QW as part of his pleadings in Kerchner v Obama. I think Gary Kreep is also going for QW. Both these attorneys are at the appeal level. We should have court rulings before the November elections on these. Then, there is David Hemenway who picked up Phillip Berg's lawsuit. One or more of these attorney's will break through this year.
Orly Taitz is being her own special prosecutor after battling the Holder/Obama Justice Department for a year. She has been financially damaged. I think she should have standing to go after Obama by now.
