The Trump Organization is a group of about 500 business entities of which Donald Trump is the sole or principal owner. Around 250 of these entities use the Trump name. The organization was founded in 1927 by Donald Trump's paternal grandmother, Elizabeth Christ Trump, and his father, Fred Trump, as E. Trump & Son. Donald Trump began leading it in 1971, renamed it around 1973, and handed off its leadership to his children in 2016 when he won the 2016 United States presidential election. The Trump Organization, through its various constituent companies and partnerships, has or has had interests in real estate development, investing, brokerage, sales and marketing, and property management. Trump Organization entities own, operate, invest in, and develop residential real estate, hotels, resorts, residential towers, and golf courses in various countries. They also operate or have operated in construction, hospitality, casinos, entertainment, book and magazine publishing, broadcast media, model management, retail, financial services, food and beverages, business education, online travel, commercial and private aviation, and beauty pageants. Trump Organization entities also own the New York television production company that produced the reality television franchise The Apprentice. Retail operations include or have included fashion apparel, jewelry and accessories, books, home furnishings, lighting products, bath textiles and accessories, bedding, home fragrance products, small leather goods, vodka, wine, barware, steaks, chocolate bars, and bottled spring water. Since the financial statements of the Trump Organization's holdings and Donald Trump's personal tax returns are both private, its true value is not publicly known, though a wide range of estimates have been made. Trump has publicly released little definitive financial documentation to confirm his valuation claims. On several occasions, Trump has been accused of deliberately inflating the valuation of Trump Organization properties through aggressive lobbying of the media (in particular the authors of the annual Forbes 400 list) to bolster his perceived net worth. By 2019, the Trump Organization was being scrutinized by New York investigators for possible financial fraud. In July 2021, New York prosecutors charged the organization with 10 counts in an alleged 15-year tax avoidance scheme. In November, The Washington Post reported that between 2011 and 2015 the organization presented several properties as being worth far more to potential lenders than to tax officials. In August 2022, the organization's chief financial officer, Allen Weisselberg, pleaded guilty to committing more than a dozen felonies, including criminal tax fraud and grand larceny. In
