WASHINGTON (Reuters) -President Donald Trump on Friday vowed to seek accountability for those who pursued him during his years out of power, speaking at the U.S. Justice Department whose prosecutors had brought some of those cases. In a rare political speech at the department's Washington headquarters, Trump painted a dark picture of its trajectory prior to his return to office in January, saying it had been co-opted by "hacks and radicals." Trump spoke to a department that twice indicted him during his years out of power on charges accusing him of illegally storing classified documents at his Florida club and plotting to overturn his defeat in the 2020 election.
