Trump appealed his requirement to have his people take part in the partisan and unfair hearings to the courts. Dems called this “obstruction of congress”.
They also made a new one called “abuse of power” which can be determined in the eye of the beholder.
They did this because they couldn’t find evidence of a crime. That’s why they were changing their charges so frequently over the past 6 weeks: quid pro quo, extortion, bribery, etc, etc.. Each time they tried something new, it failed. On top of it all, the Dems preplanned this charade with a planted whistleblower who was then never allowed to be called to testify (WB laws don’t allow for anonymity, but instead allow for protection of the WB’s job and prevent work place retribution).
This pointless foolishness will pass, but the damage done to the system over these fake charges will last generations.
