Target CEO Brain Cornell told Fortune on Wednesday that a boycott over its transgender bathroom policy was not hurting sales.

Target reiterated its policy in response to a North Carolina law approved by state Republican leaders that limits the bathroom choices of transgender people in government buildings, including schools.

The Christian conservative group American Family Association (AFA), which claims that such policies can be abused by sexual predators, said that more than 1 million people have signed a pledge to boycott the retail giant over the issue.

The retail giant blamed cold weather and skittish consumers for disappointing first-quarter sales and insisting that the purported boycott had not affected its business.

“You've heard us talk over the years about our commitment to diversity and inclusion,” Cornell told Fortune on Wednesday morning.

“To date we have not seen a material or measurable impact on our business. Just a handful of stores across the country have seen some activity and have been impacted,” he added.
