Trump tells Joe Biden he's fired before revoking his security clearance & daily briefings.

I'm very certain you don't want to go down the path of comparing the incidents with classified documents between the two as one resulted in the usual "slap on the hand" response while the other required much more. Feel free to try to prove them equivalent.

 

Adding that his comments may have been somewhat self-serving, John Brennan who was the CIA Director under Obama and had his top secret clearance withdrawn by Trump during the Donald's first term pointed out that it's not uncommon for current officials in intelligence agencies to consult with former officials on issues with which they may have had experience or expertise. Withdrawing the security clearances of retired officials limits their ability to do so. I would add that the practice was extremely rare until Trump did so in both his first term and now in his second term as a form of retribution against former officials who had the audacity to criticize the policies of the Dear Leader, John Bolton coming immediately to mind. Interestingly, Biden never revoked Bolton's security clearance even though Bolton was also critical of Biden. Within a week of taking office Trump revoked Bolton's top secret clearance as well as withdrawing his security detail which Bolton had because he was targeted for assassination by Iran.
