I’m Paul Kiel. I’ve been covering the U.S. tax system since 2018, and my latest story, reported with Russ Buettner of The New York Times, “IRS Audit of Trump Could Cost Former President More Than $100 Million” is out today. Do you remember how, as a candidate back in 2016, Donald Trump kept saying he couldn’t release his tax returns because he was under audit? Even eight years later, very little has come out about that long-running audit. So we went looking. Using publicly available sources like an IRS legal memo and info from different investigations of the former president, as well as our analysis of Trump’s leaked tax return information, we were able to piece together the first detailed look at what Trump did and why the IRS has questioned it.
