El Salvador has agreed to house violent US criminals and receive deportees of any nationality, US Secretary of State Marco Rubio announced Monday, in an unprecedented – and legally problematic deal – that has alarmed critics and rights groups.

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.

The letter claims that race-neutral practices "honor the founding ideals of this country," while diversity, equity and inclusion policies are discriminatory.
