A concert held by The Chainsmokers over the weekend is now under investigation by the New York State Health Commissioner after footage of the event appears to show a blatant disregard for protocols set by the Centers for Disease Control amid the ongoing coronavirus outbreak.

A letter sent by Governor Andrew Cuomo's office to Southampton’s Town Supervisor Jay Schneiderman demanded answers as to how such an event was ever even permitted in the first place.

According to Page Six, the letter read, "I am greatly disturbed by reports concerning the 'drive-in' concert held in your town this past weekend, which apparently involved thousands of people in close proximity, out of their vehicles, a VIP area where there was no pretense of a vehicle, and generally not adhering to social distancing guidance."

Cuomo also tweeted on Monday that he was "appalled" by the "egregious social distancing" and "reckless endangerment of public health."

Schneiderman told the outlet he plans to have a response issued by the end of the day Tuesday. He also added that his office will look into the details of the event and noted that permits were only granted for parking spaces for cars for the event. None were issued which allowed people to gather outside of them.

The event organizers, In The Know Experiences and Invisible Noise, also issued a statement following news of the investigation. They claim that they followed all of the guidelines set forth by the CDC and detailed the various ways in which they implemented it.

"Upon arrival, individuals within each car had their temperatures taken and were also provided complimentary face masks before driving to their designated 20' x 20' spot," the statement read.

They also stated that in addition to placing multiple sanitizing stations throughout the grounds, other precautions taken included "temperature checks for all attendees, sanitization of restrooms every 10 minutes, local security enforcing guests to wear their masks both in and out of their designated areas, contact tracing, clearly marked parking zones, as well as providing complimentary face masks upon arrival."
