Abortion rights groups are challenging abortion bans in some states by arguing the bans — supported by certain religious principles — violate the religious rights of people with different beliefs. Conservative Christians for decades have argued that life begins at conception and abortion should be illegal and 47 states have laws that allow health care workers to opt out of providing abortions if that violates their religious beliefs or morals. In Montana, a state lawmaker who is an ordained Jewish rabbi argues religious freedom laws that protect health care workers' religious beliefs should also protect abortion rights for those who belong to religions that support such rights.
