Did Trump and his campaign do stupid things? Yes, Trump is not a proffesional pol so he made
mistakes (appointing gutless Sessions being his biggest) and now Rats are going to try to run
him out of town for it. I am happy to see you realize this is a political witch hunt not an
"investigation". Because a real investigation would be centered on how Wikileaks got the DNC
emails. Nothing can be ascertained until that question is answered.
Funny thing about how the DNC emails were stolen - the FBI (yes, the same FBI under Comey, McCabe, Strzok, Page, et al) - offered to help and asked to look at the server. The DNC refused to cooperate.
You're also forgetting the current crop, Sessions, Rosenstein, and Wray are all Trump appointees. So, I guess this political witch hunt must be orchestrated by Republican insiders on the President's team.
