A new lawsuit filed Monday is accusing President Trump and his family of misleading investors by promoting sham businesses in exchange for money. The New York Times reports that the suit accuses Trump and three of his children—Ivanka, Eric and Donald Jr.—of endorsing “business opportunities” that were in fact schemes designed to defraud people, including the Trump Network, a vitamin marketing company, and the Trump Institute, which charged for seminars promising to reveal Trump’s real estate “secrets.”
