That is a waste of time and taxpayers dollars and, as in the case of Clinton, it made him more popular. You impeach with only one mission, to get it over to the senate where they will give him the boot. As it stands right now, there is no way the senate will go for it.
I think you need to think things through better. Just saying ...
What does the Senate have to do with impeachment? Nothing. The House does its thing and the Senate does its thing. If the Senate chooses to leave him in office so be it. Doing something including doing ones duty to uphold the Constitution is reason enough. Plus the high crimes are documented and placed into the history books as he would be the 3rd President to be impeached.
Impeach. Repeat as necessary
