On Sunday afternoon, President Barack Obama gave a commencement speech to the graduating class of students at Rutgers University in Brunswick, New Jersey. In his speech, Obama subtly references and insults presumptive GOP nominee Donald Trump multiple times without mentioning him by name. Here are a few of his quotes from the speech:

“Facts, evidence, reason, logic, an understanding of science: These are good things. These are qualities you want in people making policy. … That might seem obvious. … We traditionally have valued those things, but if you’re listening to today’s political debate, you might wonder where this strain of anti-intellectualism came from.”

“When our leaders express a disdain for facts, when they’re not held accountable for repeating falsehoods and just making stuff up, when actual experts are dismissed as elitists, then we’ve got a problem.”

“The world is more interconnected than ever before, and it’s becoming more connected every day. Building walls won’t change that. The point is: To help ourselves, we’ve got to help others, not pull up the drawbridge and try to keep the world out.”
