That's a superlative, interrupting "everyone,” which is unparliamentary.
Madam Chair, I would bring that to your attention and I would ask you to make a ruling as to whether or not that should be withdrawn.
Does Mrs. Thomas interrupt everyone? If she does, then your statement stands, but if it can be proven that she does not interrupt everyone—a superlative—then you must withdraw it.
I would ask for your ruling as the official chair of this committee.
