It’s not the cost of impeachment, but the issue of going to trial to decide whether he deserves to remain in office or turning a blind eye to possible gross misconduct.
I realize that with the current makeup of the Senate and public disclosure of how each Senator votes, conviction is unlikely (but that doesn’t mean the issue shouldn’t be addressed).
There were 2 options....turn a blind eye to what he has done in conjunction with foreign government, or put it to a test to see if enough Senators feel his actions are serious enough to warrant removal from office.

Sure and how much has he spent golfing? And how much has he given to corporations and the rich? Also how big has the deficit grown under him? And how many farmers and coal miners lost farms or their jobs because of him plus the taxpayers dollars we have given them because of Trump?

He’s a pig 🐷 lock him up!! Lock him up!! This vermin pig rat wastes more money daily than it costs to try and get justice served against him. Send the bill to Russia

this been going on since 2017. well

thinking millions?

and what's the conclusion? Turns out you cant impeach pepul ¯\_(ツ)_/¯
