He wrote on Twitter that the challenges the US has been facing will not disappear overnight, but as he looks forward to the start of a new year, he is filled with fresh hope about the possibilities of better days to come.

The president-elect's message of unity has been consistent throughout most of 2020. During the Democratic primary earlier last year, Biden maintained that he could make deals to get things done for the American people and serve as a uniting force in a country that appears to be politically divided.

Shortly after his win in the 2020 presidential election, Biden immediately called for Americans to come together as a nation.
