"The (inaugural) speech is going to be a very personal and sincere statement about his vision for the country," the incoming White House Press Secretary Sean Spicer told reporters at a news conference.
"He will discuss what it means to be an American, the challenges that we face as members of the middle class. He'll talk about infrastructure and education, our manufacturing base. I think it's going to be less of an agenda and more of a philosophical document," he said.
It is after eight years that the Republican Party has captured the White House.
Immediately after his inauguration, Trump would deliver his address to the nation. According to some media reports, it is expected to last 20 minutes.

Spicer said Trump is still working on the text of his speech.
Referring to the crowd, he said people are pouring into
Washington by the "thousands and thousands".
He said thousands turned up at the Lincoln Memorial for the "small little concert", which is unique in itself.
Talking about the campaign, Trump said, "it's a movement that began and it's a movement like we have never seen anywhere in the world. There's never been a movement like this. It's very very special".
Noting that a lot of people did not give his campaign much of a chance in the beginning, he said it was clear that something was happening in its last month.
"The polls started going up. They didn't want to give us credit," he said assuring the American people that they will not be "forgotten anymore".
As the concert concluded, the Trump family waved to the crowd from the stage before departing from the venue.
Indian-American DJ Ravidrums, who opened the concert with his percussion performance before Trump arrived, took the stage a second time, performing before the President-elect.
The concert was held at the Lincoln Memorial, an imposing historical monument that houses the 170-ton seated statue of the 16th President of the United States Abraham Lincoln.
