WASHINGTON - Former US president Donald Trump was indicted on Tuesday for his efforts to overturn the 2020 US presidential election.

It was the third time in four months that he has been criminally charged.

Trump denies any wrongdoing.

The latest development comes as he campaigns to regain the presidency in 2024.

Here is a list of legal troubles facing Trump, who is the front runner for the 2024 Republican presidential nomination.

Jan 6 and the U.S. Capitol attack

Prosecutors accused Trump in an indictment unveiled on Tuesday of conspiring to defraud the US by preventing Congress from certifying President Joe Biden’s 2020 victory and to deprive voters of their right to a fair election.

On Jan 6, 2021, Trump’s supporters attacked the US Capitol in a bid to stop Congress from certifying Mr Biden’s victory.

Prosecutors said Trump “exploited” the attack, refusing his advisers’ suggestion to send a message directing rioters to leave.

Trump and his allies advanced claims of fraud they knew to be untrue, prosecutors said. The indictment says close advisers, including senior intelligence officials, told Trump repeatedly that the election results were legitimate.

Trump and others organised fraudulent slates of electors in seven states, all of which he lost, to submit their votes to be counted and certified as official by Congress on Jan 6, the indictment said.

Trump was ordered to make an initial appearance in Washington federal court on Thursday.

Illegal retention of classified documents

Trump pleaded not guilty in federal court on June 13 in Miami to charges that he unlawfully kept classified national security documents when he left office in 2021 and lied to officials who sought to recover them.

The trial is scheduled for May 20, 2024.

Special Counsel Jack Smith accused Trump of risking national secrets by taking thousands of sensitive papers with him when he left the White House in January 2021 and storing them in a haphazard manner at his Mar-a-Lago Florida estate and his New Jersey golf club, according to the indictment.

Photos included in the indictment show boxes of documents stored on a ballroom stage, in a bathroom and strewn across a storage room floor.

Those records included information about the secretive US nuclear programme and potential vulnerabilities in the event of an attack, the indictment said.

Trump faces charges that include violations of the Espionage Act, which criminalises unauthorised possession of defence information, and conspiracy to obstruct justice.

Last Thursday, prosecutors unveiled a new indictment, which charges Trump, his co-defendant and valet Walt Nauta, and a third Trump employee, Carlos De Oliveira, with attempting to delete security camera footage at Mar-a-Lago after they were sent a grand jury subpoena for the videos in June 2022.

Prosecutors allege De Oliveira told another employee that “the boss” wanted a server containing security footage to be deleted. He has yet to enter a plea.

Georgia election-tampering criminal probe

Fulton County District Attorney Fani Willis is investigating whether Trump and others tried illegally to overturn his defeat in that state’s 2020 presidential vote. A charging decision in the criminal case is expected by Sept 1.

The investigation focuses in part on a Jan 2, 2021, phone call Trump made to Republican Georgia Secretary of State Brad Raffensperger, asking him to “find” enough votes needed to overturn Trump’s loss in Georgia.

Legal experts said Trump may have violated at least three Georgia criminal laws: conspiracy to commit election fraud, criminal solicitation to commit election fraud, and intentional interference with performance of election duties.

Trump could argue that his discussions were free speech protected by the US Constitution.

New York ‘hush money’ criminal case

A New York grand jury indicted Trump for allegedly falsifying business records in connection with a hush money payment to a porn star before the 2016 presidential polls.

Trump’s former personal lawyer Michael Cohen paid Stormy Daniels US$130,000 (S$174,000) for her silence about a sexual encounter she said she had with Trump in 2006. Prosecutors in Manhattan accuse Trump of trying to conceal a violation of election laws.

Trump pleaded not guilty to 34 counts of falsifying business records. He has denied having a sexual encounter with Daniels but admitted to reimbursing Cohen for his payment to her.

Cohen pleaded guilty to campaign finance violations and other crimes and was sentenced to three years in prison in 2018 during Trump’s presidency.

The trial is scheduled for March 25, 2024.

Sexual abuse and defamation civil lawsuits

Trump is appealing against a US$5 million verdict by a Manhattan federal jury that found him liable for sexually abusing writer E. Jean Carroll in the mid-1990s, then defaming her by lying about it in 2022.

Ms Carroll is seeking at least US$10 million more in a separate defamation lawsuit she amended after Trump blasted the verdict on CNN and on his social media platform. He has denied meeting Ms Carroll and accused her of making up her allegations.

A trial in that case is scheduled for Jan 15, 2024.

New York Attorney-General civil lawsuit

New York Attorney-General Letitia James sued Trump and his family business, the Trump Organisation, last September for alleged fraud by him and his family.

Ms James, a Democrat, accuses Trump of lying from 2011 to 2021 about asset values, including for his Mar-a-Lago estate in Florida and Trump Tower penthouse in Manhattan, as well as his own net worth, to obtain better terms from lenders and insurers.

The lawsuit seeks at least US$250 million in damages from Trump, his adult sons Donald Jr and Eric, the Trump Organisation and others, and to stop the Trumps from running businesses in New York.

A trial is scheduled for Oct 2, a date the judge has said is “set in stone”. Ms James’ office said on Monday that it has finished gathering evidence and is ready for trial. REUTERS
