The 14th Amendment says if you were involved in an insurrection you can't be president. SCOTUS said they won't allow anyone to enforce that because of reasons they made up.
The Constitution doesn't say the president is immune from criminal law. SCOTUS decided he is because of reasons they made up.
Today's opinion is as glaring an example of "originalism when we feel like it" as I can think of.
Akhil Amar--himself an originalist--will be doing a podcast on the opinion in the coming days. It will be scathing. (He already did a lot of commentary in the leadup.)

Sounds great. I don't have a well-laid-out constitutional philosophy, but to the extent that I do it tends to be "liberal originalist" as well. So I often like what Amar has to say.
