COLUMBIA, S.C. (AP) — The NAACP will introduce an emergency resolution at its national convention this weekend to lift its 15-year economic boycott of South Carolina, following the state legislature’s decision to remove the Confederate flag from Statehouse grounds.

NAACP president Cornell William Brooks said Thursday that the church massacre last month and the “brutality of this moment spoke to the country in ways that a boycott alone would not do.

“But be clear, the prospect of a bigger boycott, more economic sanctions, were effective,” he said.

The NAACP announced its statewide boycott when the flag was in front of the Statehouse in 2000. The boycott was observed by the NCAA, United Auto Workers and others.
