Bernie Sanders Says Campaigns Are Coming 'Closer and Closer Together'

Clinton's new health care plan is "significant," he said.

The rollout of this updated plan, and Sanders' support of it, was one of the last key hurdles that the two campaigns agreed to pass ahead of a potential joint event next Tuesday.

This past Wednesday, Clinton also announced a new college affordability plan that had tweaks from her former proposals. According to the campaign, the changes were the result of her meeting with Sanders.

Asked whether this meant an endorsement was imminent, Sanders said the campaigns "are coming closer and closer together." He added that he "will have more to say I think in the very new future."

Clinton announced today that she will hold an event in New Hampshire on Tuesday, but at this point there was no mention of a guest.
