Here's this from the National Republican Senatorial Committee:

What Ken Paxton has put his family through is truly repulsive and disgusting. No one should have to endure what Angela Paxton has, and we pray for her as she chooses to stand up for herself and her family during this difficult time.

That is not the kind of statement these people put out when it's a regular adultery or whatever. Whatever the "biblical grounds" are, they seem a lot more serious than usual.
