There's a decided lack of understanding in this thread about the US constitution and the role of Congress, and what this story is about. US Telecoms is a federally regulated industry. Congress does have the powers to compel testimony from individuals or companies related to this situation. If they're not satisified with the responses they can prevent them from selling into the regulated market. They don't need to engage the judiciary branch to do so.

We can argue IF this is "right" and IF these companies have been unfairly targeted, but please stop the misinformation about not having to answer to congress and requiring a court of law.
