PHILADELPHIA — Former Defense Secretary Leon Panetta was interrupted by chants of “no more war” during his prime-time speech at the Democratic National Convention Wednesday.
The chants started raining down from sections of delegates from Oregon and Washington, both states won by Sen. Bernie SandersBernie SandersGOP is consumed by Trump conspiracy theories Manchin on collision course with Warren, Sanders Sanders on Cheney drama: GOP is an 'anti-democratic cult' MORE (I-Vt.) during the Democratic presidential primary. 
Eventually, other delegates drowned them out with chants of “USA.” 
Panetta appeared flustered as he stood on stage waiting for the chants to end. 
As Panetta continued to speak, the lights were dimmed over the sections of Sanders supporters, an apparent effort to silence them. 
But the protesters were undeterred and lit up cell phone flashlights in protest.
The chants undercut a portion of the convention dedicated to promoting Clinton's national security bona fides. 
Retired Rear Adm. John Hutson's speech was also cut off by chants from the California delegation. But the chants appeared unrelated to his speech, which praised the former secretary of State's readiness to be president and attacked Trump as reckless on foreign policy.
