Ackman, a billionaire investor, said Biden has to put away his "ego" and step aside before it is too late in the 2024 presidential election cycle.

"The worst of his legacy is his ego that prevents him from stepping aside, and that's it," Ackman said. "It's his ego. And it is so wrong and so bad." ...

"I'm upset with him and upset with his family," Ackman said. "I'm upset with his wife. This is the time where the people closest to you have to put their arms around you and say, 'You know, Dad, you know, honey, you've done your thing. This is going to be your legacy, and it's not going to be a good one.'"
