Expert on Lawrence O'Donnell says no reason Trump can't pardon the entire group of insurrectionists.

20. It could seriously harm his interests if he did. It would amount to a full confession that he did

in fact foment an insurrection. That wouldn't look so good in the impeachment trial. It would likely kill what's left of his business interests and any "prestige" that he may still enjoy. He would become an absolute pariah.

It could be challenged in court and found to be a bridge too far, even for the current Supremes to go along with.

The terrorists might be "pardoned" but they would still be guilty, and their lives would become a living hell. They would be unemployable, and maybe banned for life from all manner of public transportation and accommodations, let alone airline travel. Authorities ready to pounce the minute they stepped out of line, and throw the book at them.

It would be a millstone of shame to forever hang around the neck of the Republican Party. They could never claim to stand for law and order, or Blue lives matter ever again, unless they completely disavowed Trump. They would forever be the party of a thug beating a police officer with an American flag, and getting away with it.

He could do it, but if he does, I don't think he's thought through the repercussions. Hopefully he's on a tight enough leash that he can't.
