Protests and political boycotts will reportedly clash with celebrations and festive carousing in Washington DC as Donald Trump will be sworn in as the 45th US President on 20 January.
The clash would set the tone for four "antagonistic years" between Trump's supporters and opponents.

White House pressroom to be shifted
Ahead of the oath-taking, even the largely-liberal Washington press corps was in a tizzy.
