Top advisers to U.S. President Joe Biden and President-elect Donald Trump participated in a symbolic 'passing of the torch' event focused on national security issues. The ceremony marked a peaceful transfer of power four years after Trump disputed the election result. The two sides discussed areas of harmony and worked towards a Gaza ceasefire and hostage deal. Biden's national security adviser, Jake Sullivan, passed a ceremonial baton to Trump's pick for the same job, U.S. Congressman Mike Waltz.
