IKEA, Merck and AIG are among the latest companies to join nearly 200 businesses opposed to a North Carolina law that targets the LGBT community.

House Bill 2 blocks local municipalities from enacting LGBT protections and prohibits transgender people – including students – from using the bathroom of their choice in government buildings.

Also signing on this week to an open letter calling on Republican Governor Pat McCrory to repeal House Bill 2 are 23andMe, Instacart, The Honest Company, United Guaranty Corporation, Cabot Creamery, Castlight Health, Inc., Willis Towers Watson, Allscripts Healthcare Solutions, Inc., Yadkin Bank and Direct Marketing Association.

“Discrimination is wrong, and we believe it has no place in North Carolina or anywhere in our country,” the letter, organized by HRC and Equality North Carolina, states. “As companies that pride ourselves on being inclusive and welcoming to all, we strongly urge you and the leadership of North Carolina's legislature to repeal this law in the upcoming legislative session.”

Since the letter's introduction in March, lawmakers have returned to work. Republican leaders, however, continue to publicly defend the law.
