Fearing possible gunfire, it only took the collapse of a police barrier at a celebrity music show in New York, politically charged, Saturday, to send thousands of spectators on the run.

Approximately 60,000 people filled the park's large lawn for the eight-hour Global Citizen Festival. They listened to the well-known figures of New York Democratic Governor Andrew Cuomo and Republican Senator Jeff Flake, as well as Janet Jackson and John Legend, all of whom urged spectators to get involved in the country's troubled politics.

Suddenly, just before 8 pm, the police barrier to contain the crowd rocked, releasing a sound that terrified many spectators.

The authorities spoke quickly, assuring the crowd that they were safe.

Hot questions of social justice dominated the eight hours that began on a sunny afternoon. We have also planned Cardi B, The Weeknd and other pop stars.

Some speakers have asked the audience to call on members of Congress to respond to this week's Senate hearings for Supreme Court nominee Brett Kavanaugh.

"We want equal justice and a full investigation for the Supreme Court candidate, not limited time investigations, not limited scope investigations," Cuomo said. "And that means that, before bringing a person to the Supreme Court to administer justice, we want to make sure justice is done."

In a video, the former first lady, Michelle Obama, urged people to sign up to vote in the mid-term elections on November 6th.

Outside the show, Senator Christopher Coons, a Delaware Democrat, called Flake a "true hero" after Friday's testimony, which prompted Arizona's Republican to call for an FBI inquiry into charges.

During a break in the Senate session on Friday, Coons said in New York Saturday that "Flake's first comment when we went backstage in the antechamber was that this country is torn apart and I deeply respect a ton of pressure to demand a break of a week and a thorough background check of the FBI. "
