The brief interaction, which created moments after the oath of office, attracted praise for Barron’s polite demeanor.

The inauguration was organized on January 20 at the Capitol Building, where the 78-year-old Trump took the oath administered by Supreme Court Chief Justice John Roberts.

With his right hand raised, President Trump was sworn in while his wife, Melania, held two significant Bibles: one given to him by his mother and the other, the famed Lincoln Bible historically used by Abraham Lincoln in 1861.

All members of the Trump family, including sons Eric and Donald Trump Jr. and daughter Ivanka Trump attended the event in the Capitol Rotunda.

It was the youngest, Barron, who drew attention to his appearance.

He was seen politely offering a handshake to then-outgoing President Joe Biden and former Vice President Kamala Harris after his father was sworn in.

According to Jeremy Freeman said that the 18-year-old greeted Mr. Biden with a cordial “G’day to you, sir,” then turned to Kamala Harris and said, “Ma’am, good day.”

A video of Barron’s respectful gesture caused a fuss on X (formerly Twitter), as uploaded by the Irish Star, with many applauding his “class.”

One commenter wrote, “Barron has been raised right,” while another lightheartedly suggested, “Barron Trump 2044 campaign starts now.”

User Miss Meg commented him “a classy, well brought-up young man” and adding, “As a mother, I am moved. God bless him.”
