Donald Trump has been sworn in as the 45th president of the United States. In his inaugural address, he promised to give the government back to the people and put "only America first."

The remarks, which Trump previously said he wrote himself, reiterated many of his campaign promises, RT reported.

"America will start winning again, like never before. We will bring back our jobs, we will bring back our border, we will bring our wealth, we will bring back our dreams," said Trump.

"We do not seek to impose our way of life on anyone but as an example," Trump said.

He then promised to unite the civilized world against radical terrorism, which we will eradicate. We will rediscover our loyalty to each other.

"When America is united, America is totally unstoppable," he said.

The speech lasted 16 minutes, about half as long as the average inaugural address.
