Impeachment resolutions made by members of the House of Representatives are turned over to the House Judiciary Committee which decides whether the resolution and its allegations of wrongdoing by the President merits a referral to the full House for a vote on launching 'a formal impeachment inquiry.
The entire House of Representatives votes for or against a formal impeachment inquiry, needing only a simple majority (a single vote) for approval.
If approved, the House Judiciary Committee conducts an 'investigation" to determine (similar to a grand jury) if there is enough evidence to warrant articles of impeachment (indictments) against the President.
The Committee then drafts articles of impeachment pertaining to specific charges supported by 'the evidence'.
The Committee votes on 'each' article of impeachment, deciding whether to refer each article to the full House for a vote....If the House Judiciary Committee refers one or more articles of impeachment, the entire House of Representatives votes on whether the article(s) merit a trial in the Senate, needing only a simple majority for approval.
If the full House approves 'at least one' article of impeachment, the President is technically impeached and the matter is referred to the U.S. Senate.......
WHERE IT WILL DIE ON THE VINE!
Could Mitch just declare it a B.S. political witch hunt and refuse to proceed, or would he have to call for a Senate trial?
