The reports I heard indicated she didn't want to be questioned on her run-in with the Capitol Hill Police. That may be, but it also shows an arrogant disregard for her constituency not to mention her opponents.
And now, apparently, she isn't even responding to news media attention. Methinks there's something in play here more than a bruised ego. Does she have stability problems, perhaps?
Yes, her sense of absolute entitlement (fueled by dopes like the KOmmie KOoks) has unbalanced whatever brain she started out with.
