While still giving remarks before the ceremony, Trump told his top advisers that they are in the White House not to 'help ourselves' but to 'devote ourselves to the national good.'

'This is not about party, this is not about ideology. This is about country, our country. It's about serving the American people,' he said.

'Public service is a high and great calling, it's our solemn duty, together, to protect the country, our country, this great, great country.

'To defend its workers and promote the well being of all Americans. So many people are depending on us and on you as families, as people that are going to get it done. So many people. The veterans.

'The unemployed. Men and women serving in harm's way overseas. Victims of crime and young Americans looking to fulfill their dreams.'
