New York City officially entered phase four of reopening Monday with low-risk outdoor, arts and entertainment, professional sports with no spectators and media production.

Mayor Bill de Blasio says the city has been on the right path and worked hard to lower COVID-19 numbers.

Despite the success, the mayor spoke out against the recent overcrowding and large groups reported in Astoria, Queens. The mayor says the city has zero tolerance for those who do not social distance.
