Donald Trump was wearing his signature red power tie this morning, as he left Blair House to kick off Inauguration Day. 

The soon-to-be 45th President of the United States was accompanied by his wife Melania, who channeled Jackie Kennedy in a chic powder blue dress with matching jacket, gloves and pumps.

All of his children were in attendance with him Friday morning, except his youngest son Barron, age 10.  

In a phone call with Good Morning America on Friday, the mogul-turned-politician's eldest son Donald Trump Jr said he was raring to get the day's events going.  

'He's doing great. He doing well. He's just excited to do this,' Donald Jr said of his father. 'He's amazed and thrilled that the American people have intrusted him to take this country in a different direction - to bring it forward and to do things and to give them that voice that he mentioned last night, that has been gone for so long. So it's just truly incredible.'
