Democratic House candidate Dan McCready’s spouse has claimed over $50,000 in tax credits since 2016 under a controversial North Carolina business incentive program, according to state records, even as her husband runs in opposition to tax loopholes.

McCready, who is running against Republican Dan Bishop and has also been in talks with Senate Majority Leader Chuck Schumer about a potential 2020 Senate bid, has criticized loopholes that allow companies and wealthy individuals to lower their tax rate, arguing that the overwhelming amount of tax credits benefit the upper class. “I don’t think that it’s right, right now, that a billionaire like Warren Buffet is paying a lower tax rate than a teacher,” he said during a campaign event in April.
