Former US President Donald Trump is due to address tens of thousands of his supporters at two rallies today before he's formally arrested. 

Mr Trump is due to address supporters rallies in both Georgia and North Carolina on Saturday. 

Mr Trump has been charged with mishandling hundreds of classified documents after leaving office in 2021 - some relating to US nuclear secrets and military plans. 

The indictment includes accusations that Mr Trump had classified documents detailing the defence and weapon capabilities of the US and other foreign states, the US nuclear programme, and the “potential vulnerabilities” of the US.  

The 49-page indictment carries 37 charges, with some charges carrying a 20-year prison sentence.

Special Counsel Jack Smith is leading the investigation. 

“The laws that protect National Defence Information are critical for the safety and security of the United States and they must be enforced,” he said. “Violations of those laws put our country at risk.”

Former US prosecutor Michael McAuliffe said Mr Trump is facing many worrying charges concerning the safety of the US.  

“It’s like you have two buckets,” he said. “You have having and possessing the records improperly. 

“And then the second is that he intentionally misled and obstructed the process. So, it looks like the indictment contains both types of charges.” 

Mr Trump, who previously announced he would run in the next presidential election, has maintained his innocence. 

“The corrupt Biden Administration has informed my attorneys that I have been indicted, seemingly over the Boxes Hoax,” he wrote.
