In an internal email to the Trump Organization obtained by The New York Times, Mr. Danziger thanked the Trump family for always being “incredibly supportive,” adding, “I will always cherish my time here.”
Mr. Trump’s company, the Trump Organization, did not immediately respond to a request for comment.
Mr. Danziger’s tenure coincided with a period of deep turmoil for the business, including a series of congressional and law enforcement investigations that put a crimp in expansion plans.
His departure is part of a broader reshuffling of the company’s executive ranks. Mr. Trump’s longtime chief financial officer, Allen H. Weisselberg, lost his title last year after he was indicted, along with the Trump Organization itself, on tax fraud charges. Mr. Weisselberg remains at the company in a lesser role.
The moves put what was already a tight-knit company further in the hands of the Trump family. Mr. Trump, once he became president, largely turned over the company to his son Eric, who already oversaw its generally successful golf division.
Since leaving office, Mr. Trump has leveraged his political popularity in some quarters to pursue entirely new business endeavors, from a social media platform to a multimillion-dollar advance on a $75 coffee table book. These lines of revenue are separate from the Trump Organization’s core real estate business, which includes the hotels, 16 golf clubs and a variety of commercial real estate properties that have been among its biggest moneymakers.
