At the ripe age of 78, Donald Trump was inaugurated today (January 20) at the Capitol building by Supreme Court Chief Justice John Roberts.

With his right hand elevated, Trump swore in while his wife, Melania, stood by holding two weighty tomes: one a gift from his mother and the other, the revered Lincoln Bible that historical figures like Abraham Lincoln utilised back in 1861.

Before the ceremony unfolded, Trumps family procession made their way into the Capitol Rotunda, finding their seats in anticipation of the impending inauguration. The gathering featured his sons Eric Trump and Donald Trump Jr, as well as his daughter Ivanka Trump.

But it was the youngest Barron who caught the attention of viewers who praised him for his politeness. He was seen extending a courteous handshake to then-outgoing President Joe Biden and former Vice-President Kamala Harris following his father’s swearing-in.

Lip reader Jeremy Freeman revealed that the 18-year-old cordially greeted Mr Biden with “G’day to you sir”, before turning to Kamala Harris and saying, “Ma’am, good day”.

President Trump descended upon Washington on Saturday to revel in the company of kin, backers and political cohorts as they rallied before his second inauguration.

Making the journey from West Palm, Florida, Trump was accompanied by Melania Trump and their son Barron on a US military C-32 plane, signified as Special Air Mission 47 an allusion to his succession as the 47th president.

In his inaugural speech, President Trump declared that during his governance “our sovereignty will be reclaimed. Our safety will be restored. The scales of justice will be rebalanced”.
