The “obstruction” charge fails because there’s a reasonable debate to be had over applying “executive privilege” and SCOTUS agreed to have that debate.
House Dems jumped the gun by pushing “obstruction” while failing to follow the legally prescribed process for this particular “abuse” charge, which culminates in an obligatory SCOTUS filing.
Neither Article reached the necessary Supreme Court review. Impeachment is DOA on that alone, dismissible with prejudice (”take it away and don’t bring it back”).
Agreed, obstruction fails since they didn’t pursue the court remedy.
I don’t think they are required to file abuse charges with SCOTUS first. But if they have to make a case on how he abused his office. I don’t think a case made on he was looking at democrat corruption is going to fly.
