McConnell's vow of a rigged trial gives Dems an opening. They can try to force votes on fairer rules, and call for admission of new evidence, putting vulnerable Rs in a tough spot. Expert@mollyereynolds  helps explain the process. @paulwaldman1  and me:

Trump is now attacking Biden as mentally unfit. Meanwhile, Trump's towering pathologies are impairing our response to a public health emergency. This absurdity is made possible by the massive media failure to reckon with Trump's own unfitness. New piece:

1) As Trump ends the year with a flood of lies about his wall, we need to recapture a core truth about this presidency. Trump isn't “twisting the truth” or “stubbornly refusing to admit error.” Trump is engaged in *disinformation.* This is a different thing entirely. *THREAD*

1) This is extraordinary. Sinclair is now reportedly requiring dozens of local stations to air a segment that defends the tear-gassing of migrants and describes them as an “invasion of our country.” I’m not sure we’ve figured out how to conceptualize this adequately. *THREAD*

Trump has now publicly admitted that his attorney general intervened in the case of his own longtime adviser -- who obstructed an investigation into an attack on our political system -- for the express purpose of undermining DOJ's own investigative conclusions about himself.
