In his first hours as president, Joe Biden will aim to strike at the heart of President Donald Trump’s policy legacy, signing a series of executive actions that reverse his predecessor’s orders on immigration, climate change and handling of the coronavirus pandemic.

Joe Biden swears the oath of office at noon Wednesday to become the 46th president of the United States, taking the helm of a deeply divided nation and inheriting a confluence of crises arguably greater than any faced by his predecessors.

Donald Trump pumped his fist and waved as he departed the White House on Marine One Wednesday for the last time as president, leaving behind a legacy of chaos and tumult and a nation bitterly divided.
