No, there's a reason that people like you recoil at the very thought of those people having to answer questions under oath...
There most certainly is. The republican idea of doing this is to distract. Nothing more. And it is a childish attempt that anyone who cares to be objective can easily see. Call Obama.
The thing is Big Steve is that the people who this ploy fools are the ones not intelligent or engaged enough in the process to care.
Just for the record, in the United States, we do not go on legal fishing expeditions. The real question is, why muddy the waters? Try Trump then, if the republicans dare, go after the others. They have subpoena power in the senate. Why have they not done it before? We all know why. It is because they do not think anything is there but they have no problem using distraction to convince their dullard followers that there is.
At the end of all of this nonsense, we need to take a look at our schools. So many people without the basic constitutional knowledge to fight a traffic ticket....not to mention vote.
