I agree with Texasgurl. Rather than make dubious allegations against anonymous senators, I would appreciate it if you got specific. Name names, Senator.
I third the requests of Senators StevenNick and TexasGurl for Mr. Nation to name names.
It was the demand to name names that pushed McCarthy to produce the names of innocent people and ruin their lives. People just couldn't accept vague accusations, (that later proved true) they demanded unnecessary specifics.
I believe it is better for the Senator to make his point without making it a personal one. Those in question already know who they are.
