WASHINGTON (Reuters) -U.S. Special Counsel Jack Smith on Friday asked a federal judge to delay the start of former President Donald Trump's trial on charges of willful retention of classified government records and obstruction of justice until Dec. 11, a court filing showed. On Tuesday, U.S. District Judge Aileen Cannon set an initial trial date of Aug. 14. Trump, who is seeking the Republican nomination for president for the 2024 election, was arraigned in federal court in Miami last week, during which he pleaded not guilty to charges he unlawfully kept national security documents when he left office and lied to officials who sought to recover them.
