Donald Trump was sworn in as the new President of the United States with fans wondering whether Manchester United's anthem was sung at Capitol Hill.

For more than 100 years, the US did not inaugurate its president until March - a four month wait for the official handing over of power. That changed in 1933 during the Great Depression economic crisis, when Inauguration Day moved from 4 March 4 to 20 January - with the ratification of the 20th amendment to the US Constitution.
