I think you're mistaken, albaby. The evidence is simply that Biden told Zients et al. to decide who to pardon. There is no evidence, testimonial or otherwise, that Biden did any final review of any of the specific individuals that Zients et al. thought should be pardoned, except of course Biden's own family members (perhaps). Since Biden did not actually execute any individual pardon, and did not actually authorize any individual pardons (except perhaps his family members), at best he unconstitutionally delegated the pardon authority to his subordinates.

If you actually have any specific testimony from Biden or anyone else to the contrary, I'd be interested. As I said in my prior post, I'm not aware of any.

I believe in the Rule of Law. The pardon power is exclusively the President's and cannot be constitutionally delegated to his subordinates.
