"The tone of the new charges was apparent from the first paragraph of Mr. Smith’s filing, which described Mr. Trump as 'a candidate for president of the United States in 2020.'"

"The original indictment had referred to him as 'the 45th President of the United States and a candidate for re-election in 2020.'... Perhaps the most significant change between the 36-page superseding indictment and the original 45-page indictment was that Mr. Smith’s deputies removed all allegations concerning Mr. Trump’s attempts to strong-arm the Justice Department into supporting his false claims that the election had been rigged against him. The initial charging document accused Mr. Trump of conspiring with Jeffrey Clark, a loyalist within the Justice Department who had promised to launch 'sham election crime investigations' and to 'influence state legislatures' to back Mr. Trump’s false claims of election fraud.But in its ruling on immunity, the Supreme Court effectively struck those accusations from the case.... [T]he court decided, a president’s dealings with the department were part of the core official duties of his office and, for that reason, were immune from prosecution."
