CHARLOTTE - Hillary Clinton on Friday postponed a visit to Charlotte, hours after the city's mayor urged presidential candidates to delay planned visits as the city began to heal in the wake of a fatal police shooting.

Thanking Clinton and her Republican rival, Donald Trump, for their public support, Mayor Jennifer Roberts asked the pair to wait before bringing politics to the city. "If there would be a way to delay those visits in terms of giving us a chance to get our city back to order and back to more of a state of normalcy, that would probably be ideal." she said in an interview with CNN.

In a statement late Friday, Clinton's communications director Jennifer Palmieri said that the Democratic candidate would "postpone Sunday's trip as to not impact the city's resources."

There was no word from the Trump campaign on any planned visit to the city.

Several hundred protesters marched through Charlotte for a fourth night Friday, many of them reacting to a newly released video showing the final moments of 43-year-old Keith Lamont Scott shot by police on Tuesday. The footage included the sound of Scott's wife, Rakeyia, pleading with officers not to shoot and begging him to get out of his truck.

As police continue to refuse to release their internal footage of the incident, the video offered a raw look at how the situation unfolded but failed to show whether the man had a gun, as police have said.

Friday's march began just after 8 p.m., chanting loud into the night as they moved through the downtown area, flanked, but never bothered, by police. "This is a marathon. This is a marathon that started when they put us on their slave ships," Janaya Khan, one of the protest leaders, told the marchers.

Charlotte is the latest U.S. city to be shaken by protests and recriminations over the death of a black man at the hands of police, a list that includes Baltimore, Milwaukee, Chicago, New York and Ferguson, Mo. In Tulsa on Thursday, prosecutors charged a white officer with manslaughter for killing an unarmed black man on a city street last week.

Charlotte-Mecklenburg Police Capt. Mike Campagna said Friday afternoon that officers planned to allow the protesters peaceful passage down the streets. "We are going to facilitate," he said. He attributed the relative calm of the protests Thursday and Friday nights compared with earlier days to the people of Charlotte seeing what happens when things turn violent. When events did become tense, he said, the key was communication. "A lot of it was talking to people. A lot of it was listening to people."

After three days of protests, downtown Charlotte had remained quiet. Restaurants and stores at the Epic Center, usually bustling at this time, said they were told to close at 4 p.m.

"I just didn't think I could feel any worse," said Roger Long, a longtime Charlotte resident as he was being hustled out of a CVS store. The windows of the CVS were still boarded up from previous nights of protests. The video raises more questions about why police felt compelled to shoot Scott, he said.

As the protesters moved through the night, Melita Mullis followed at the back, the retired nurse sitting in a wheelchair pushed by her daughter, Tina. A Charlotte resident of more than 20 years, she said she had not attended a protest since the 1960s.

"We believe in the movement, the police have to find other options than shooting people," she said. "We want transparency."
