She comingled technologies and made a careful refetence to minitutaruation... TI too much information and when in a committee position it becomes a statement. Even things know may not be speculative generalizations by members.
She didn’t make a “careful reference” to miniaturization, she merely used the word without providing any context, detail, or evidence that she knows much about it. Mere usage of the word “miniaturization” in reference to ballistic missile warheads is not classified, it is common usage.
There is nothing in her comments that appears classified or that she could possibly be in trouble over. It is a very generic, innocuous kind of statement.
