When Bruce Springsteen canceled a concert in Greensboro, N.C., last weekend to protest a state law that many said curbed gay and transgender rights, it was only the latest fallout from the measure. Like similar legislation in Mississippi, it has drawn criticism across the country.

The rock star joined politicians, municipalities and businesses that had withdrawn cultural events, projects and official travel to North Carolina, dealing symbolic and economic blows to the state because of the new law, which bars transgender people from using public bathrooms that do not match the sex on their birth certificates.

“Some things are more important than a rock show and this fight against prejudice and bigotry — which is happening as I write — is one of them,” Mr. Springsteen said in a statement.

Here are some other key developments in the two states.
