US President Donald Trump has revoked security clearances and access to classified information for former President Joe Biden, former vice-president Kamala Harris, former presidential candidate Hillary Clinton, and other political opponents, in what is seen as a campaign of retribution against his critics. Trump's memo also includes members of the Biden family and other political and legal figures who had prosecuted him. Retribution has been a recurring theme in Trump's presidency, and he has recently targeted law firms, universities, and media figures who have opposed him. Even prominent anti-Trump media figures are seeking truces with the President.
