NBA Commissioner Adam Silver said Thursday that the league needs a resolution to a North Carolina law that targets the LGBT community by the end of summer for the 2017 All-Star Game to remain in Charlotte.

Speaking to reporters in Oakland before Game 1 of the NBA finals, Silver reiterated the NBA's opposition to the controversial law.

Lawmakers approved and Republican Governor Pat McCrory signed House Bill 2 during a one-day special session convened in March. The law blocks cities from enacting LGBT protections and bars transgender people from using the bathroom of their choice in government buildings, including schools.

Silver said that he needed to see definitive progress by the end of summer to ensure Charlotte remains the host city.

“I don't see how we would get past this summer without knowing definitively where we stand,” Silver said.

Several entertainers have canceled performances in North Carolina to protest House Bill 2.

“I think both sides of the issue recognize, however heartfelt their views are, that the current state of being is causing enormous economic damage to the state,” Silver said.

Silver said that the league was looking at the “core principles” of inclusion and diversity.

“I think there are other fundamental issues that I think if we can work through with the community to ensure those basic protections are given to the LGBT community,” Silver said. “I think if we can make progress there, we will see you all in Charlotte next February.”
