Former President Barack Obama bluntly urged Democrats nervous about the state of the party’s primary field to “chill out” on Thursday, stressing that while there are differences between the numerous Democrats running for president, those differences are “relatively minor” compared to what the Trump administration is doing.

The comments from Obama build on a series of statements the former President has made about the race for his old job, injecting the popular Democrat into a nomination fight that he had largely avoided.

“Everybody needs to chill out about the candidates, but gin up about the prospect of rallying behind whoever emerges from this process,” Obama said after a lengthy answer that defend the arduous primary process that Democrats are currently in.
