I support Mr.President .Donald Trump

@LesDeplorable: no, I am not part of a 'movement'. I just want to know the truth about whether the President was involved in treason. I realize it's not a important as, say, getting a blow job while president. Still, sunlight is the best disinfectant.

I think you are making things up as you go along. An inquiry is undertaken to ascertain the facts. Congress does not need 'probable cause' to launch an inquiry. You don't know much about the law, do you?

Congress decides what fact-finding and investigation is needed to perform its duties. No probable cause needed. No smoking gun needed. That doesn't prevent Congress from looking for a smoking gun.

Here's an overview of the subject:

??? Not sure what that means.

The link worked fine for me. Try cutting and pasting it into your browser. Or you can retake my word for it. Congress has the power to vote on impeachment. That gives it the broad powers to investigate what Trump knew and when he knew it.

The only reason they need is that the information sought may be relevant to the powers granted the legislature. In this case, since Congress can impeach a sitting President, they can investigate whether there is evidence to do so. They don't need evidence to launch an investigation. Gathering the facts is the whole point of the power to investigate.

Yes. Read the article I cited.

@LesDeplorable: I read the article you cited. It recited various investigations by Congress. That's about it. It did not in any way suggest that there must be probable cause before calling for an investigation or conducting one. I repeat, all Congress needs to justify an investigation is that the subject or goal of the investigation relates to a subject upon which Congress may take action. It's a very broad power.
