Republicans repeatedly have advanced bad-faith arguments and dropped them when they proved too ridiculous to sustain, only to move on to a new argument, equally spurious. Yes, Trump had raised the Bidens during the July 25 call. Yes, Trump was pressuring a foreign power, using his personal lawyer, Rudolph W. Giuliani, to help him manufacture dirt on a rival. The next category of bad-faith arguments concerns the Senate’s apparent refusal to call available witnesses and documents. Simply saying “Democrats want witnesses, Republicans do not” is to give Republicans’ arguments credence they do not warrant.
