US President Donald Trump has used his inaugural address to say that "together we will determine the course of America and the world for many, many years to come".

He said Americans have "joined a great national effort to build our country and restore its promise for all people".

It began to rain in Washington as Mr Trump started speaking, moments after being sworn in as the 45th president of the United States on the West Front of the US Capitol.

Mr Trump also thanked all of the past presidents in attendance, including Barack Obama and Bill Clinton.

Mr Trump said change starts "right here and right now".

The new president used his inaugural address to say it does not matter which party controls the government.

He said that what matters is "whether our government is controlled by the people".

Mr Trump said the forgotten men and women of the country "will be forgotten no longer".

He said: "Today we are not merely transferring power from one administration to another," but "transferring power from Washington DC and giving it back to you, the people."

Mr Trump said that, for too long, too few have had power and the people have paid the price.

He said: "Washington flourished but the people did not share in its wealth.

"Politicians prospered but the jobs left and the factories closed."

He said: "That all changes, starting right here and right now."

Mr Trump also thanked Mr Obama and former first lady Michelle Obama for their "gracious" aid through the transition.
