What do you think I'm hiding?
Not you personally...
Congress conducted the inquiry and were clearly obstructed illegally by the WH.
They were prevented from getting evidence and having the witnesses they wanted.
This was an investigation.
Now we get to the trial. The prosecution should be allowed to call witnesses and present evidence OR this is not a trial.
You can try and sell anything to US public but don't claim that this is transparent. The GOP Senate is covering up for what looks like a more and more guilty President.
Innocent people want transparency and shed light on things, guilty want to hide things...
