The exchange began when Sanders tweeted out a video of him speaking with reporters and one asks him if he thinks Clinton is a progressive.
"Some days, yes," the Vermont senator responds. "Except when she announces that she is a proud moderate, and then I guess she is not a progressive."
Clinton responded with a video of her own on Twitter that showed her at a rally touting her progressive achievements.
"It was kind of a low blow when Sen. Sanders said, in response to a question, 'Well maybe she's a progressive on some days,'" she said in the video.
Sanders then shot back with a chain of tweets that began with him saying, "You can be a moderate. You can be a progressive. But you cannot be a moderate and a progressive."
The exchange came hours before the two are scheduled to appear at a CNN town hall in Derry, N.H. Their campaigns have agreed to three news ones, all of which will be sanctioned by the Democratic National Committee.
