Democratic presidential hopeful Bernie Sanders on Sunday did not directly answer a question about whether it was appropriate for actress Rosario Dawson, a Sanders surrogate, to mention former White House intern Monica Lewinsky at a rally Saturday.

{mosads}“Rosario is a great actress and she’s doing a great job for us,” Sanders said Sunday on CNN’s “State of the Union.” “I have no idea in what context Rosario is talking about, but I would hope that all of our people talk about the real issue.”

Sanders also said people should be talking about climate change instead of his surrogate.

“And, by the way, it might be a good idea for all of us, including TV networks, to start talking about the planetary crisis of climate change,” Sanders added.

Dawson on Saturday took a swipe at Sanders’s rival, Hillary Clinton, by mentioning Lewinsky — who has become an anti-bullying activist following her alleged affair with former President Bill Clinton — and accusing the front-runner’s campaign of bullying.

“We are literally under attack for not just supporting the other candidate,” Dawson said. “Now I’m with Monica Lewinsky with this: Bullying is bad.”
