The American version of Christianity has decided that a fetus is a person, and as such that an abortion is murder. They make it this emotional issue so that people don't think too hard about it and just reflexively think "I can't support murder!"
This is despite the Bible pretty explicitly defining life as beginning at the first breath, and treating causing a miscarriage as property damage.
It's part and parcel of the Republican party essentially taking over the church and getting people to equate "Republican" with "Christian".
It's also a redundant department. There is already the Government Accountability Office, which literally does the same job (but probably actually does it efficiently).
