PHILADELPHIA — The tension between Bernie Sanders activists and Democratic Party brass set to crown Hillary Clinton their nominee lingered in pockets of Philadelphia as the final day of the convention dawned.

Actors and delegates took center stage in smaller and more subdued protests by Bernie Sanders supporters on a mostly quiet Day 3 of the Democratic National Convention.

Susan Sarandon, Danny Glover, Shailene Woodley and Rosario Dawson joined forces as night fell to protest what they consider slights against loyalists of Sanders, a Vermont U.S. senator who competed against Hillary Clinton in the party’s presidential primaries before endorsing her.

Sarandon said convention organizers scuttled planned remarks from prominent Sanders surrogate Nina Turner, a former Ohio state senator, at the convention on Tuesday night.

“There’s been a lot of difficulty in executing the will of Bernie Sanders’ people and surrogates, and this was just a topping for the whole thing because she was ready to go. And she was very, very disappointed,” Sarandon said as the other celebrities joined her on a platform. “This has not gone by lightly, and … we are upset.”

Late Wednesday, hundreds of protesters gathered outside the convention site as Vice President Joe Biden, vice presidential nominee Tim Kaine and President Barack Obama spoke inside. There were two distinct groups of protesters; one peaceful, the other anti-government. At one point a protester’s clothes caught on fire while trying to stomp out the flames on a burning flag. The protester dropped to the ground and rolled around to put the fire out. Another tense moment arose when protesters knocked over part of a security fence, but police quickly moved in and put the fence back up. The Secret Service said seven people were arrested and will be charged with entering a restricted area. A group of peaceful protesters then sat on the ground and sang as the tension in the streets dropped back to normal.

Earlier in the day, half a dozen Sanders delegates spoke to about 300 demonstrators gathered at a plaza near City Hall, about 4 miles from the convention site, for rallies and speeches.

Erika Onsrud, an at-large delegate from Minnesota, told the people in the crowd that they need to continue to fight. Amid cheers, she exhorted them: “Stay awake!”

Other delegates acknowledged that Sanders’ loss was disappointing but told the supporters that they can create change without the Democratic Party and the mainstream media, contending the media contributed to a rigged election.

A few blocks away, police detained 10 protesters at Comcast’s corporate headquarters for holding a sit-in accusing the cable TV giant and NBC owner of not reporting the truth. The demonstrators locked themselves with zip-ties to a rolling gate inside the building. Officers briefly closed the 975-foot-tall skyscraper to all but Comcast employees. All 10 protesters were ticketed and released.

Another group of about a dozen anti-Israel demonstrators protested at a hotel where a number of delegations to the four-day convention were staying. They called for a free Palestine.

The absence of marches was a marked change from earlier in the week, with some Sanders supporters saying their comrades seemed fatigued and frustrated.

Thousands of activists have taken to the streets during the convention to voice support for Sanders and his liberal agenda. On Tuesday night, the Bernie or Bust brigades watched in dismay as Clinton became the first woman nominated for president by a major U.S. political party.
