Here is a look at what Trump has done since his inauguration as US President last Friday.
Building the Mexico-US border wall
One of Trump’s most controversial campaign promises was the vow to make Mexico build a “beautiful wall” on the US-Mexico border.
Earlier this week, he signed an executive order for “impassable physical barrier” and told the press that Mexico would reimburse America.
Mexico has slapped down a suggestion by Trump’s administration that America could impose a 20% tax on Mexican imports to pay for the wall.
