WASHINGTON, Aug 26 (Reuters) - Former President Donald Trump has raised nearly US$20 million in the past three weeks, a period that roughly coincides with his indictment in federal and state cases connected to his false claims that the 2020 election was stolen from him, Trump's campaign spokesman said on Saturday,

Since appearing Thursday to have his mugshot taken in a racketeering and fraud case in Atlanta, Georgia, the former president brought in US$7.1 million, Trump spokesman Steven Cheung said on X, the platform formerly known as Twitter.

On Friday alone, Trump brought in US$4.18 million, making it the highest-grossing day of his campaign so far, Cheung said.

Trump, who was elected president in 2016 but defeated by Democrat Joe Biden in 2020, is again seeking the Republican Party's nomination for President.

Trump is currently facing four indictments related to his false claims that the election was stolen, and the Jan 6, 2021 attack by his followers on the US Capitol in Washington, DC.

He has denied all charges.

On Aug 15, Trump was indicted by a Georgia grand jury after an investigation by Fulton County District Attorney Fani Willis into his efforts to overturn his 2020 election loss to Biden in the state.

On Aug 3, he pleaded not guilty to charges brought by Special Counsel Jack Smith in federal court in Washington that he conspired to defraud the United States by preventing Congress from certifying Biden's 2020 election victory over him and to deprive voters of their right to a fair election.

He has also pleaded not guilty to charges of unlawfully keeping classified documents after leaving office, and of falsifying business records in a case in New York related to the payment of so-called hush money to porn star Stormy Daniels before the 2016 presidential election.
