evidence: WASHINGTON (AP) — Donald Trump laid the groundwork to try to overturn the 2020 election even before he lost, knowingly pushed false claims of voter fraud and "resorted to crimes" in his failed bid to cling to power, according to a court filing unsealed Wednesday that offers new evidence from the landmark criminal case against the former president. [...] The filing was submitted, initially under seal, following a Supreme Court opinion that conferred broad immunity on former presidents for official acts they take in office, a decision that narrowed the scope of the prosecution and eliminated the possibility of a trial before next month’s election. [...] Prosecutors also alleged that Trump advanced claims of fraud despite knowing they were false, recounting how he conceded to others that allegations of election irregularities made by attorney Sidney Powell were "crazy" and referenced the science fiction series "Star Trek." Even so, days later, he promoted on Twitter a lawsuit she was about to file.
