Former US President Donald Trump, during a Republican Party rally, attacked what he called the "corrupt political establishment", in the first gathering in front of his supporters since announcing his candidacy for the presidency.

Trump, 76, delivered a speech to Republican activists and lawmakers in New Hampshire, saying, "We need a leader who is ready to confront the forces that are wreaking havoc on our country." The first to take office.

The two gatherings are seen as an opportunity for Trump to revitalize his faltering campaign, amid criticism for not organizing events since he announced last November his intention to run for the 2024 US presidential election.

Trump repeated his accusations that the 2020 elections were stolen from him, and directed insults at his political rivals, but his most prominent criticism was against his Republican opponents, whom he considered "more dangerous than the Democrats."

He also praised his record in the field of law enforcement, imposing order, combating immigration and "rebuilding" the US military, pledging to save the country from "destruction at the hands of a selfish, radical and corrupt political establishment," as he put it.

Trump is reported to be struggling to maintain a base of support in South Carolina, given his endorsement of defeated candidates in November's midterm elections.

A race may end up between Trump and Florida Governor Ron DeSantis over the ticket to run for the Republican Party, but polls at this early stage of the race do not always give a clear picture of the scene, as some results showed Trump's superiority over DeSantis, and others showed the opposite result.

The biggest hurdle in Trump's path to the Republican nomination appears to be his mounting legal troubles, with a "special investigator" appointed to look into numerous allegations of misconduct.

"These are extreme left prosecutors, and they are absolutely horrible people," Trump said, vowing to investigate the activities of the Justice Department if he is re-elected.

Light is currently being shed on Trump's dealings with secret documents that were found during the FBI's search of his residence in Florida, his role in storming the Congressional Building in 2021, and his attempts to overturn the results after his defeat in the state of Georgia in the 2020 elections. .
