According to the AP account in the Seattle Times:
"Roberts cut her off by saying that if she had documents with her, she should give them to security officers. He also said he could not discuss the issue."
Quite different from Taitz's account of the incident, which also brings into question her story of what it is Scalia said when she gave a similar performance at his speech. Unfortunately, there wasn't any press report on Scalia's speech that I've seen.
The Video or audio tapes of the Q/A will tell the tale if it ever becomes available. I don’t doubt she said several things trying to preface her question but I remain skeptical of the Chief Justice holding a discourse in public with her about this case or mischarachterising his protection as a Secret Service Agent.
