It's why Texas Attorney General Ken Paxton, in a recent letter signed by 18 other Republican attorneys general, called on Costco to end its DEI policies. Just this month, Costco shareholders overwhelmingly voted down a proposal that would have examined the impact of DEI on company operations.

Led by Texas Attorney General Ken Paxton and Iowa Attorney General Brenna Bird, the Republican officials instructed Costco to let them know within 30 days whether it would get rid of its DEI policies or explain why not. Costco did not immediately respond to a request for comment.

"Although Costco’s motto is 'do the right thing,' it appears that the company is doing the wrong thing—clinging to DEI policies that courts and businesses have rejected as illegal," the letter reads.
