President-elect Trump’s Inauguration Day is less than a week away and he’s begun to plan who will attend various events in Washington to mark his return to the White House. Trump has invited many other people, including Chinese President Xi Jinping and Hungarian Prime Minister Viktor Orban, but it’s not known if they will come to the U.S. to welcome Trump back to office. Here’s who is confirmed to attend Trump’s inauguration so far: President Biden President Biden announced last month he would attend Trump’s inauguration. He said, “Of course” he would attend and said the only outgoing president not to attend the ceremony was Trump himself, when he lost to Biden in 2020. Former first lady Melania Trump did not attend Biden’s inauguration either. Former President Obama Former President Obama will attend the Jan. 20 ceremony, but his wife, former first lady Michelle Obama, will not. In a statement, the Obama family said the former president would be attending Trump’s second inauguration. The statement did not provide an explanation for her absence. Her decision not to attend Trump’s inauguration breaks the tradition among most former presidents and their wives, besides the Trumps in 2020. Obama recently sat next to Trump at former President Carter’s funeral last week. The two noticeably shared a laugh and conversation at the ceremony. Former President Bush and former first lady Laura Bush Former President Bush and former first lady Laura Bush will attend, his office said, The Associated Press reported. Former President Clinton and former Secretary of State Hillary Clinton Former President Clinton and former Secretary of State Hillary Clinton will also attend the ceremony next week. Hillary Clinton notably attended Trump’s first inauguration in 2017 after she lost the 2016 presidential election to him. Elon Musk Elon Musk, who has been tapped to co-lead Trump’s “Department of Government Efficiency,” will be in Washington to attend the inauguration. Musk, who donated millions to Trump’s campaign, has become a close ally of the presidents-elect. There’s concern about Musk’s influence over Trump as the tech billionaire continues to engage politically with Trump ahead of the inauguration. Jeff Bezos Amazon owner Jeff Bezos will also be in attendance, The Washington Post reported. Bezos also owns the aerospace company Blue Origin and recently expressed optimism about the new Trump administration’s space policy. Mark Zuckerberg Meta CEO Mark Zuckerberg will attend the inauguration, seated next to Bezos and Musk. The tech trio are expected to be seated near the other former presidents, Trump’s family, lawmakers, and his Cabinet picks, which is a prominent seat for the group, the Post reported.
