The Chainsmokers are facing intense criticism and an investigation after headlining a large concert in the Hamptons this past weekend.

Video shows thousands at the Water Mill charity drive-in show on Saturday night. Many people appear to be ignoring "safe zones" around their vehicles and not wearing masks.

Gov. Andrew Cuomo tweeted, "Videos from a concert held in Southampton on Saturday show egregious social distancing violations. I am appalled. The Department of Health will conduct an investigation. We have no tolerance for the illegal & reckless endangerment of public health."

"There's a square around the space, that's socially distanced, fine," says Cuomo. "That's not what the concert was in the Hamptons."

Southampton Town Supervisor Jay Schneiderman and his band opened the concert. The state health commissioner sent him a letter demanding answers.

Schneiderman told Newsday the problem was a VIP area that was not authorized by the town, and says concert organizers are being cited. He says according to the permit issued, attendees could get out of their car but had to stay in designated space unless they were going to a restroom.

In a statement released to Billboard, the concert organizers "In The Know Experiences" said, "The video that everyone is talking about was taken from an angle that doesn't properly convey how careful we were to follow the guidelines created by the CDC. We did everything in our power to enforce New York's social distancing guidelines and collaborated with all state and local health officials to keep everyone safe."

Organizers say the clip shows the band's friends and family area separated by barricades with only 10 people allowed inside. Town officials say gathering areas were not allowed under the permit.

"I noticed that some people were being allowed into that area. I said something to the security staff. I said I have to leave, but you can't do that," says Schneiderman.

Schneiderman says shortly after, town police shut down the concert.

The state Health Department is also investigating.
