“We condemn that,” Sanders said. “We want our supporters to be [talking] about the issues.

“[We] don't need ugly, personal attacks against Sen. Warren, or anyone else for that measure,” he added.

He said he had a cordial discussion with Warren as she reassesses her campaign, but would not discuss the private conversation with his colleague and opponent.

Warren had no public events Wednesday after a disappointing finish in the 15 races held the day prior. Her campaign said it was taking a day to assess whether Warren still has a path to a nomination.

Asked whether he would consider Warren as a running mate, Sanders said it’s “too early to talk about that.”

However, he said he would "love to sit down and talk to her about what kind of role she could pay in our administration,” adding that he has a lot of respect for the senator.
