You can't make this shit up: Biden makes a bizarre joke about his uncle eaten by cannibals, a reporter asks why Biden does that, Biden's Press Sec scolds the reporter for making a joke about Biden's joke and... blames Trump.
If Biden has got significant limitations on his memory, then who is helping him run the country? Biden's Press Sec: "That part of the report does not live in reality." Biden: "Aafuthimerfutifuterwigh!"
