'Quite bizarre': Kamala Harris reacts to Donald Trump's 'father of IVF' claim

“I’m going to say what I’ve said publicly and what I’ve said many times based on my observations. … Donald Trump is increasingly unstable, and as has been said by people who have worked closely with him even when he was president, he’s unfit to be president of the United States,” Kamala Harris said as she also questioned what Donald Trump meant by 'I am the father of IVF' comment.
