Donald Trump was inaugurated as America’s 47th president in a ceremony that was held inside the Capitol Rotunda because of freezing conditions outside. On his first day Mr Trump signed orders withdrawing America from the Paris climate agreement and the World Health Organisation, and revived sanctions on the International Criminal Court. He also declared an emergency at the border with Mexico, tasking the Department of Defence to come up with a plan to seal it and repel “invasion” from mass migration and trafficking. Refugee admissions were suspended and a scheme that allowed people from Cuba, Haiti, Nicaragua and Venezuela to move temporarily to America was ended.
