You might want to read this book by a Trump executive. I read it years ago. Try as he might to make Trump look bad - just couldn't do it. Trump and the mob, and Trump and Ivanna (he was very supportive). Trump gave Ivanna her own casino that was competitive with his. Great description of who got the high rollers and how they were handled.
TRUMP in Atlantic City: The rise and fall of the Trump Casino Empire
by Ron Alcorn (Author)
As the last giant red TRUMP sign is taken down in Atlantic City in early 2017, Donald J. Trump has just been sworn in as the nation's 45th President. An inside look at the Trump Atlantic City years, from the opening of Harrah's at Trump Plaza in 1984 until the closing of the Trump Taj Mahal in 2016. This book recounts the author's twenty-plus years working as a Vice President at Trump Taj Mahal and Trump Plaza in Atlantic City. He tracks the Trump Organization from the heady days of the Taj Mahal in the 1990's to the decline and closure of the last casino bearing Trump's name in 2017. The author's many interactions with Donald Trump over the years are detailed throughout that time period, along with an inside look at how the Trump casinos were managed.
