Former US President Donald Trump has compared himself to the late anti-apartheid activist Nelson Mandela as he addressed his legal issues in a speech at his latest campaign rally.

Trump likened himself to the former South Africa’s President on Monday as he claimed he is being targeted by federal and state prosecutors because of his politics, Sky News reports.

The former American leader is currently facing four criminal indictments and numerous civil trials relating to a range of allegations – though they have not stopped him from seeking a return to the White House.

Trump, who was in New Hampshire to register for its presidential primary, held a rally where he attacked his successor Joe Biden’s response to the Israel-Hamas conflict and vowed to build an Iron Dome-inspired defence shield over the States.

However, he focused much of his speech on the criminal and civil cases against him – and suggested he could go to prison as Mandela did.

“I don’t mind being Nelson Mandela because I’m doing it for a reason,” Trump told revved-up supporters in Derry, New Hampshire.

“We’ve got to save our country from these fascists, these lunatics that we’re dealing with. They’re horrible people and they’re destroying our country.”

Mandela, who died in 2013, spent 27 years behind bars for opposing South Africa’s apartheid system. In 1993, he was awarded the Nobel Peace Prize.

Allegations against Trump include the claim that he inflated his net worth and misclassified hush money payments made to women during his 2016 presidential campaign.

He is also alleged to have stored classified documents at his Mar-a-Lago club and illegally tried to overturn his 2020 election loss.

Turning his attention to the US President, Trump told the rally that Biden’s recent speech on the conflict in the Middle East was “a grotesque betrayal of Israel” and “one of the most dangerous and deluded speeches ever delivered from the Oval Office”.

His comments came after he formally filed for the first-in-the-nation primary, where he wrote “Vote for Trump and solve your problems” on the commemorative poster in Concord that all candidates will be asked to sign.
