Sen. Bernie Sanders (I-VT) told Hillary Clinton Saturday night that he was sorry about a data breach that occurred earlier in the week when his campaign temporarily accessed Clinton campaign data.

“Not only do I apologize to secretary Clinton, and I hope we can work together on an independent investigation from day one,” Sanders said. “I want to apologize to my supporters. This is not the type of campaign that we run. And if I find anybody else involved in this, they will also be fired.”

Former Secretary of State Hillary Clinton accepted that apology.

It was the only time the issue entered into the debate. The exchange lasted just mere minutes after dominating the news cycle Friday.

Sanders went on to ask Clinton to participate in an independent investigation to ensure that her campaign had also not accessed Sanders’ campaign data during a previous data breach.

“I look forward to working with secretary Clinton for an investigation, an independent investigation about all of the breaches that have occurred from day one in this campaign because I am not convinced that information from our campaign may not have ended up in her campaign,” Sanders said. “Don’t know that. But we need an independent investigation, and I hope secretary Clinton will agree with me for the need of that.”

Clinton seemed to imply she had already agreed to move forward with that.

“It really is important that we go forward on this. I know that you now have your data back and that there has been an agreement for an independent inquiry into what did happen,” Clinton said.
