Trump doesn't give a shit about abortion, trans rights, or even immigrants. He doesn't care about America or making it great. For him, all of those things are just convenient distractions.
Even if Biden hadn't blazed the blanket pardont rail, you can bet Trump would have anyway, for himself and his buddies. I'm sure he's thrilled that Biden blazed the trail, because nobody will be able to challenge his without also challenging Biden's.
