That's a huge red flag. Just asking the question in an interview situation leaves them open to unfair discrimination lawsuits, and you can easily get a negotiated settlement whenever they end the interview process.

I would find the time to have a brief consultation with a lawyer familiar with workplace & EEO law, and hear what they think.

Note that EEO law usually aren't regulated (companies don't need to show they are in compliance, and government agencies don't conduct spot checks with 'mystery candidates'); they have to fear the punishment of a settlement in order to abide with the law. If they're a tiny fly-by-night company they might just close up and re-establish elsewhere to avoid the suit.
