Adoni Media’s Leisa Goddard says a doctor would have a “field day” assessing US President Joe Biden’s cognitive capabilities.

“You would have to be living under a rock in the US if you were not across the fiasco … he fails a cognitive test nearly every time he is out in public never mind a physical test of walking up steps,” she said.

“You could just tick them off, a doctor would have a field day with those.”
