McCarthy s dragging his feet because he doesn’t have the votes. He doesn’t have the votes because the House Republican “majority” is made of a bunch of weak sisters who don’t deserve to be sitting on a county board much less in Congress.
McCarthy is not a lawyer. However, it makes some sense to have as many answers as possible before asking pertinent questions germane to an impeachment. if he doesn’t have the votes at this point in time, then the task becomes herding the cats in the proper direction. the most expedient and effective way to do this might be to exert appropriate influence over the court of public opinion, such as through financial bank records.
one possible question is how much money Biden paid for each of his mcMansions. If he paid full market value, this can be disclosed in bank records; a legitimate followup would be to ask where the money came from given Biden’s Congressional salary at the time. If he did not pay full market value, why, and who did he buy the mansions from? If I were forced to bet, I would wager on the latter (and another round of questioning on the mcMansion sellers), since buying real estate at below market prices seems to be a common way to buy political influence these days.
