US President Barack Obama, speaking at an event in New York City, said that a bias against powerful women could hurt Democratic presidential nominee Hillary Clinton with voters in November.
"There's a reason why we haven't had a woman president," Obama said at the fundraiser for Clinton. "We as a society still grapple with what it means to see powerful women and it still troubles us in a lot of ways, unfairly."
In his brief remarks, Obama touted his Administration's achievements over the past eight years, praised Clinton and blasted Republican nominee Donald Trump as unfit to be president as he has repeatedly in recent weeks.
His remarks about Americans' reluctance to support a powerful woman were among his strongest on the subject and come amid polls showing that the race is tightening.
"This should not be a close election but it will be, and the reason it will be is not because of Hillary's flaws," he said.
