Ok...guys.....may I? I have looked into this for many years after investigating the impeachment of President Bill Clinton.
According to the articles of impeachment, a submission must be brought forth to, initially, the House of Representatives accusing the current president of "crimes and misdemeanors".
There is now an independent investigator in the form of Robert Muller.
If his investigations show a knowing cooperation between the Russian government and the Trump Campaign, all he can do is record and present.
Once it has been made clear to the House of Representatives, it is up to them to act in whatever direction they are most comfortable with.
Will that mean articles of impeachment are drawn up?
Actually no........I don't think that will happen.
The current conservative based majority in the House of Representatives will explain it away.
