President Donald Trump has not wasted any time as President by bringing in a number of new laws.
Many of the laws he has bought in were areas he promised to change while he was campaigning to become President.
Within days of taking control he stopped entry into the US for people from seven Muslim-majority countries.
The exact implications of his order remain unclear, but it includes people from Iran, Iraq, Libya, Somalia, Sudan and Yemen. People fleeing Syria are banned until further notice.
He has also pass laws saying the US wont be involved in the Trans Pacific Partnership. The TPP is a trade agreement between countries within the Pacific.
He has also started working on the wall he promised to build between Mexico and the southern states of America. This has resulted in the Mexican President cancelling a trip to Washington to meet President Trump.
