It doesn't have anything to do with Trump or Biden. SCOTUS has been ruling that religious people get to choose what laws they want to follow for 15 years+ now.
It's not in limbo either - if right wing religious people don't want to follow a law they don't have to according to SCOTUS.
Hell, in my lifetime we've gone from 'the state may not fund private, religious education' to 'the state MAY fund private, religious education' to 'the state MUST fund private religious education'.
If so why is the HHS reviewing his opinion? Trump admin's amendments included birth control and HIV preventative medication. These were thrusted upon companies before the ruling. I'm not sure why you're hyper focused on it always being doable when it clearly wasn't until Trump came into office and changed the rules through his hhs. The ruling is simple, companies aren't on the hook to offer plans that included preventative care and zero cost medication. His admin's HHS also issued two rules on birth control and other similar contraceptive drugs and devices.
The only issue with this is his admin later, as in near the end of his term developed a program to get these services to people without insurance, and those with terrible insurance would pay a fraction. It came full circle with Cuban's new drug company offering generics and name brands at cutthroat rates compared to regular pharmacies.
Like I said, if they didn't want to follow the law why did they go to court over getting this struck from the aca? Why waste so much money in legal fees when you didn't have to do anything? They're moving towards repealing any decent humane rule of law we've pushed forward in the last 15 years. Even Bush is too liberal for them now.
