Nine South Carolina Republicans who had co-sponsored one of the most severe anti-abortion proposals in the country have since withdrawn their support, reversing course on a measure that proposes applying the state’s homicide laws to people who undergo abortions.

The legislation, which had a total of 24 co-sponsors — all Republicans — since its introduction in January, lost support from nine of them in recent weeks.

Reps. Kathy Landing and Matt Leber were the first to pull back support in late February.
