Joe Biden is being shunned from lucrative engagements on the public speaking circuit, a report claims.

Instead of travelling on private jets and speaking at glitzy awards shows, Mr Biden is spending his post-presidency years talking aloud in the train’s quiet carriage, collecting takeaway meals from his favourite diner, and browsing the aisles of menswear shops.

Companies have become reluctant to hire the former president as a paid speaker in fear it may spark backlash from Donald Trump, who has not shied away from lambasting businesses that platform his opponents, the Wall Street Journal (WSJ) reported.

There is also concern over Mr Biden’s health, capacity to give coherent speeches, and dwindling popularity in Democratic circles, who now view him as a liability to his own party amid rumours the former president’s declining cognitive state was covered up by the White House.

Since leaving office, Mr Biden has been beset with financial headaches. According to the WSJ, he reportedly confided in someone that he intended to pay off around $800,000 in personal debt he had accumulated.

The Bidens have also been hit with a 20 per cent increase in their property taxes on their Delaware beach home this year, public records show.
