Former US president Donald Trump has been criticized for calling for the "abolition" of portions of the US Constitution in light of his claims that the 2020 presidential election was stolen.

Mr. Trump, who declared his candidacy for president last month, made the claim on his Truth Social platform over the weekend.

He wrote, "A Massive Fraud of this type and magnitude permits the termination of all rules, regulations, and articles, including those in the Constitution."

"Our great 'Founders' did not want false and fraudulent elections and would not have tolerated them!"

On Sunday, the incoming Democratic leader of the House, Hakeem Jeffries, described Mr. Trump's statement as bizarre and extreme and said that Republicans will have to decide whether to continue supporting Mr. Trump's anti-democratic views.

"Republicans will have to resolve their differences with the former president and decide whether they will break with him and return to some semblance of reasonableness or continue to embrace the extremism of not only Trump, but Trumpism," said Mr. Jeffries.

Mr. Trump, who is the first US president to be impeached twice and whose term ended with his supporters violently storming the Capitol in a deadly attempt to halt the peaceful transition of power in 2021, faces escalating criminal investigations, several of which could result in indictments.

They include the investigation into classified documents seized by the FBI from his Mar-a-Lago estate in Florida, as well as ongoing state and federal probes into efforts to overturn the results of the 2020 presidential election.

Mr. Trump's remarks followed Elon Musk's announcement that he would reveal how Twitter suppressed free speech leading up to the 2020 election.

However, documents released on Friday, which focused on the tech company's muddled response to a story about President Joe Biden's son Hunter, do not demonstrate that Democrats attempted to limit the story.

The White House attacked Mr. Trump on Saturday, declaring, "You cannot only love America when you win."

"The American Constitution is a sacred document that has guaranteed freedom and the rule of law in our great nation for over two centuries," said spokesman Andrew Bates in a statement.

"Attacking the Constitution and all that it represents is antithetical to our nation's soul."
