Lara Trump captivated the crowd at Donald Trump's New Year's Eve party with her performance of Tom Petty's 'I Won't Back Down'. Elon Musk, JD Vance, and the president-elect himself were among the attendees who watched in awe. Lara's father-in-law, Donald Trump, seemed focused on the song, while Melania stood closely behind him. The rest of the crowd sang along and recorded the performance on their phones. The exclusive party had around 300 guests, including Donald Trump Jr. and his new girlfriend Bettina Anderson. President-elect Trump answered questions from the media before entering the event, expressing confidence in his Cabinet nominees and demanding the release of Hamas' Israeli hostages.
