This is absolute fake news. The SC doesn’t call private meetings to proactively discuss political matters, i.e., any matter or action taken anywhere by anyone which may eventually become the subject of appeal before it. It doesn’t meet to discuss anything but the case(s) before it. It doesn’t announce ANY meetings at all nor the particular cases which might be discussed. This is just another indication of fuckery afoot regarding the status of RBG.
