This isn't a trial. It is an investigation. The purpose of an investigation is to gather evidence. When all of the evidence has been gathered it will be shared. They haven't even finished conducting interviews.
An investigation of what? What is the probable cause?
It is a perpetual fishing expedition, intended SOLELY to delay, distract, impede and block the Republican's agenda.
That agenda includes massive cuts to federal spending, increases to military spending, Obamacare repeal/replace, greater border enforcement, education choice, and other reforms that real conservatives have asked for for years.
Anybody claiming to be conservative, Trump voter or not, ought to be opposed to blocking the Republican agenda.
