Donald John Trump Jr. (born December 31, 1977), often nicknamed Don Jr., is an American businessman and political activist. He is the eldest child of Donald Trump, the 45th and 47th president of the United States, and his first wife, Ivana Trump. Trump is a trustee and executive vice president of the Trump Organization, running the company alongside his younger brother Eric. During their father's first presidency, the brothers continued to engage in deals and investments in foreign countries and collect payments at their U.S. properties from foreign governments, despite pledging not to do so. He was a boardroom judge on the reality TV show featuring his father, The Apprentice. 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. Trump campaigned for several Republicans during the 2018 midterm elections. Trump was also active in his father's 2020 presidential campaign, often on the campaign trail and featured in the news for making unfounded claims. During the election, he called for "total war" as the results were counted and promoted the stolen election conspiracy theory. Following his father's defeat, he engaged in attempts to overturn the results. 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." Trump has authored two books: Triggered in 2019 and Liberal Privilege in 2020. In 2023, he launched a podcast, Triggered with Don Jr. In 2024, Trump joined the venture capital firm 1789 Capital as a partner and joined the board of directors of Credova.
