President Joe Biden gave a plan for the United States to combat the climate crisis.

Jane Goodall doesn't change her opinion on Donald Trump.

The behavior of the presidential candidate was compared to that of a male chimp.

In an interview with MSNBC's Ari Melber that aired on Tuesday, Goodall agreed with that view.

Melber played a video of Trump hugging and kissing the American flag in front of Hillary Clinton during one of their 2016 presidential debates.

What are you seeing there? Melber wanted to know what Goodall thought.

When a male chimp is competing for dominance with another, he will show the same kind of behavior that Goodall sees in a female chimp.

They project themselves as more large and aggressive than they actually are in order to intimidate their rivals.

The divisiveness created in America by Trump and others can have a negative effect on the world.
