I'm somewhat optimistic that Garland's DOJ is still working its way up the food chain, attempting to strike deals, with the aim of minimizing the chance that a case brought against Trump fails in court, which would really be a catastrophic outcome.
I hope that is the case. Tribe, who was Garland's professor at Harvard, said of the hearings this week: “It greatly strengthens the case, particularly with respect to Trump’s direct involvement in fomenting the violence of the insurrection itself. The evidence that emerged was very powerful, indicating that [the riot] was anything but spontaneous, that he was fully aware at the time the unhinged meeting at the White House ended at around midnight on 18 December that his only remaining alternative was essentially to pull the trigger and issue the tweet at 1.42 in the morning, which included the dramatic call to action."
Tribe has also been quoted as saying Garland is incredibly slow.
