Donald Trump, Jr., American businessman and son of billionaire Donald Trump
Donald John Trump Jr. (born December 31, 1977) is an American political activist, businessman, author, and former television presenter. He is the eldest child of the 45th president of the United States, Donald Trump, and his first wife businesswoman Ivana Trump.

Trump serves as a trustee and executive vice president of The Trump Organization, running the company alongside his younger brother Eric. During their father's presidency, the brothers continued to do deals and investments in foreign countries, as well as collect payments in their U.S. properties from foreign governments, despite a pledge that they would not do so. Trump also served as a boardroom judge on his father's TV show The Apprentice. He authored Triggered in 2019 and Liberal Privilege in 2020.

Trump was active in his father's 2016 presidential campaign. He cooperated with Russia in their interference in the 2016 United States elections and had a meeting with a Russian lawyer who promised damaging information about the campaign of Hillary Clinton in the 2016 presidential election. He has promoted several conspiracy theories. Trump has engaged in attempts to overturn the 2020 United States presidential election following his father's electoral defeat; he has promoted the stolen election conspiracy theory and advocated "total war" instead of completion of vote counting. He spoke at the rally that led to the storming of the Capitol, where he threatened Trump's opponents that "we're coming for you." On January 11, 2021, Attorney General for the District of Columbia Karl Racine said that he is looking at whether to charge Donald Trump Jr. with inciting the violent attack on the U.S. Capitol in the criminal investigation into the attack.
