Prosecute those who covered up his mental decline. Start with the ones in the media.

"The media covered up the biggest scandal in presidential history… and now they’re cashing in on it. We were told @JoeBiden
was sharp as a tack, and any evidence that proved otherwise was a “cheap fake,” but now that the Democrats lost and the dust has settled -- reporters are selling off all of their dirt in brand-new books. Biden's secrets are coming at us like a fire hose. Today we’re finding out Biden's right-hand man, Ron Klain, told author, @ccwhip
, that Joe was mentally and physically shot. Klain helped Biden prepare for the debate… and what he saw scared him. Biden didn’t have anything to campaign on so he came with this strategy: look confused while Trump was talking so voters would quote “understand that Trump was an idiot.” Boy, did that backfire."
