Actors Susan Sarandon, Danny Glover and Rosario Dawson are protesting what they see as slights against Bernie Sanders supporters at the Democratic convention in Philadelphia.

The celebrities all expressed their anger that Nina Turner was barred from addressing the crowd.

Sarandon said Wednesday eveningconvention organizers scuttled planned remarks from the prominent Sanders surrogate.

Turner is a former state senator from Ohio who hoped to announce Sanders' nomination Tuesday night even if rival Hillary Clinton had the votes to win.

The Dead Man Walking and Thelma and Louise star said convention organizers are making it difficult to carry out 'the will of Bernie Sanders' people.'

Actress Rosario Dawson was another celebrity who was angry about how Bernie Sanders and his 'surrogates' had been treated in Philadelphia

'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.'

Lethal Weapon actor Glover added: 'This particular convention has been unlike any convention in decades in this country.

'Certainly with the voices here at the table from all places. We need to know that those voices are heard, including and especially the voice of Nina Turner.'

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 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 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. Officers zip-tied them and briefly closed the 975-foot-tall skyscraper to all but Comcast employees. The demonstrators 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.

Sarandon said convention organizers are making it difficult to carry out 'the will of Bernie Sanders' people.'

Sarandon said the disappointment she shared with other celebrities has not 'gone by lightly'

Demonstrator Shannon Morgan, who's from suburban New York, said she's fatigued by political frustration, long days and hot pavement that burned through the soles of her Vans and scorched the bottoms of her feet.

She described herself as an anarchist socialist and said she can't understand why Sanders supporters are still singing and cheering.

'I don't believe in burning things down,' she said, but she added it's frustrating 'to see them still happy and not storm the convention center and sit in.'

The longstanding bitterness between Sanders' supporters and Clinton's seemed to grow worse over the past few days after a trove of hacked emails showed that officials at the Democratic National Committee played favorites during the primaries and sought to undermine Sanders' campaign.

Sanders on Monday criticized Republican presidential nominee Donald Trump and urged supporters to fall in line behind Clinton for the good of the country. But many were unmoved.

Thousands gathered in the streets outside the convention at the Wells Fargo Center on Tuesday night, and some tried to scale the 8-foot walls around a restricted zone. Police and the Secret Service arrested four protesters.

As of midday Wednesday, only about 75 people were at the nearby park that has become a base for the protesters.

Jennifer Hall flew into Philadelphia from California and said her fellow Sanders supporters seemed tired. She said she came to 'comfort the heartbroken, mourn with the mourners and help sustain the effort' fighting against two-party politics.
