By many measures, Chobani embodies the classic American immigrant success story.
Its founder, Hamdi Ulukaya, is a Turkish immigrant of Kurdish descent. He bought a defunct yogurt factory in upstate New York, added a facility in Twin Falls, Idaho, and now employs about 2,000 people making Greek yogurt.
But in this contentious election season, the extreme right has a problem with Chobani: In its view, too many of those employees are refugees.
As Mr. Ulukaya has stepped up his advocacy — employing more than 300 refugees in his factories, starting a foundation to help migrants, and traveling to the Greek island of Lesbos to witness the crisis firsthand — he and his company have been targeted with racist attacks on social media and conspiratorial articles on websites including Breitbart News.
