No but people said they saw her at a concert that had no promotion, and offered  live stream that was posted on the internet after the concert was over. The most credible evidence was a Supreme Court transcript from February 19 where she was recorded as having asked a question or two.

The fact that the Wapo doesn't trot over there and resolve the issue is pretty troubling.
