An analysis by USA Today published in June 2016 found that over the previous three decades, United States president Donald Trump and his businesses have been involved in 3,500 legal cases in U.S. federal courts and state court, an unprecedented number for a U.S. presidential candidate.[1] Of the 3,500 suits, Trump or one of his companies were plaintiffs in 1,900; defendants in 1,450; and bankruptcy, third party, or other in 150.[1] Trump was named in at least 169 suits in federal court.[2] Over 150 other cases were in the Seventeenth Judicial Circuit Court of Florida (covering Broward County, Florida) since 1983.[3] In about 500 cases, judges dismissed plaintiffs' claims against Trump. In hundreds more, cases ended with the available public record unclear about the resolution.[1] Where there was a clear resolution, Trump won 451 times, and lost 38.[4]
The topics of the legal cases include contract disputes, defamation claims, and allegations of sexual harassment. Trump's companies have been involved in more than 100 tax disputes, and on "at least three dozen" occasions the New York State Department of Taxation and Finance has obtained tax liens against Trump properties for nonpayment of taxes.[1] On a number of occasions, Trump has threatened legal action but did not ultimately follow through.[5]
Of Trump's involvement in the lawsuits, his lawyer Alan Garten said in 2015 that this was "a natural part of doing business in [the United States]",[5][6] and in the real estate industry, litigation to enforce contracts and resolve business disputes is indeed common.[5] Trump has, however, been involved in far more litigation than fellow real-estate magnates; the USA Today analysis in 2016 found that Trump had been involved in legal disputes more than Edward J. DeBartolo Jr., Donald Bren, Stephen M. Ross, Sam Zell, and Larry Silverstein combined.[1]
