Just as a point of clarification, I believe within the protocol it is not permissible for a reporter, a member of the press, to come and interrupt a member sitting in a committee meeting. Is that correct?
If that is the correct protocol, and it certainly must be understood by the reporters who work on the Hill day after day, then there was a breach of protocol by that reporter who did approach a member. Whether she caught him by surprise or not, she bears a lot of the responsibility.
This committee, if she's breached protocol, would be well in its right to issue a complaint via the Speaker, or directly against her, and remind her of the protocol and not to let it happen again.
