Clegg, a former British deputy prime minister, said he is stepping down, citing the new year as the right time to move on. He'll be replaced by Kaplan, who will take on the title of chief global affairs officer.
Kaplan was White House deputy chief of staff under former President George W. Bush, and he appeared at the New York Stock Exchange with Vice President-elect JD Vance and Trump in December. He also attended Supreme Court Justice Brett Kavanaugh's confirmation hearing in 2018 as a personal friend, causing a controversy for the social media company.
