COLUMBIA, S.C. (AP) — A proposed map of new South Carolina Senate lines based on 2020 U.S. Census data moves one district from Richland County to faster-growing Charleston County.

But the map appears to keep most other senators in their current districts.

A committee of senators gave preliminary approval to the new map Thursday. They plan a public hearing on the new districts on Nov. 12 and the entire Senate could consider redistricting at a special session in December.

The biggest change is taking the Senate district currently represented by Democratic Sen. Dick Harpootlian of Columbia and moving it to Charleston.
