Nick Vaidyanathan of Seattle helped shout down former CIA director Leon Panetta at the Democratic National Convention on Wednesday night – and he's not sorry about it.

The Bernie Sanders delegate said the chant "No More War" began in the Oregon delegation as Panetta took the podium.

"I thought it was a very positive message," he said Thursday morning. "It's not a personal attack, it's not a denigration. It's really a statement of the people's perspective when it comes to this issue."

As the chant grew louder and persisted, Panetta appeared rattled. Then the house lights over the protesters were turned off.

"Some ingenious people over there actually lifted their cell phones and got their flashes going so they could still be seen," Vaidyanathan said.
