West was discussing his support for Trump and questioning why people go after the president instead of trying "love" when Kimmel pointed to the policy that separated families caught crossing the border illegally. "The question was so important I took time to think".
West considered the question, sitting silently without answering before Kimmel took a commercial break. "You've so famously and so powerfully said, 'George Bush doesn't care about black people, '" Kimmel said.

He also landed in hot water this May when he said slavery "sounds like a choice".
"It represented overcoming fear and doing what you felt no matter what anyone said, and saying 'you can't bully me, '" West said. It's like we're mentally imprisoned'.

On Saturday, West said there was no hard feelings between him and Kimmel despite their differing views.
Kimmel then insisted that he actually didn't need to answer that but the Life Of Pablo hitmaker stood firm.
