Without mentioning President Donald Trump by name, Obama emphasized his belief in facts.
"Unlike some, I actually try to state facts — I believe in facts — I believe in a fact-based reality, a fact-based politics," he said at the University of Nevada, Las Vegas rally. "I don’t believe in just making stuff up. I think you should say what’s true."
