WASHINGTON (AP) — Former President Donald Trump may face an IRS bill in excess of $100 million after a government audit indicates he double-dipped on tax losses tied to a Chicago skyscraper, according to a report by The New York Times and ProPublica that drew on a yearslong audit and public filings.

The report’s findings could put renewed focus on Trump’s business career as the presumptive Republican nominee tries to regain the White House after losing in 2020.

Trump used his cachet as a real estate developer and TV star to build a political movement, yet he has refused to release his tax filings as past presidential candidates have. The tax filings that the public does know about have come from past reporting by the Times and a public release of records by Democrats on the House Ways and Means Committee in 2022.

Trump’s presidential campaign provided a statement in son Eric Trump’s name saying the IRS inquiry “was settled years ago, only to be brought back to life once my father ran for office. We are confident in our position.”
