“He is a man with a very low IQ, our president. “I’m willing to bet that of all the presidents – and we’ve had many – Joe Biden is the president with the lowest IQ of all time,” RIA Novosti quotes Trump as saying.
Johns Hopkins University professor, surgeon Marty Macari, in an interview with Fox, argued that the US President is showing signs of progressive age-related dementia.
Biden himself called himself the most experienced US presidential candidate of all time and said that he was in the prime of his life.
At the same time, the personal physician of Biden's predecessors as head of state, Barack Obama and Donald Trump, member of the United States House of Representatives Ronny Jackson believes that the US president needs to pass a number of tests for cognitive abilities before participating in the elections.
