Donald Trump was sworn in for a second term as president of the United States on 18th January. The 78-year-old made a historic return to the White House, four years after his previous re-election attempt. Trump, the first U.S. president to serve after overcoming legal challenges, replaced incumbent Democrat Joe Biden following a decisive victory over outgoing Vice President Kamala Harris in November's presidential election. Triumphing over significant obstacles, Trump secured another term, with plans to transform the country's institutions. U.S. tech billionaires, including Elon Musk, Mark Zuckerberg have expressed interest in collaborating with his administration to drive innovation and progress.
