Republican lawmakers inserted several medical exceptions into Kentucky's near-total abortion ban on Thursday, seeking to offer clarity to doctors fearful of breaking the law for terminating pregnancies while treating expectant mothers with grave complications.

Republicans pushed an unexpected update to Kentucky’s abortion ban through the state legislature this week, passing it in less than 24 hours.
