We have some dangerously cold temperatures out there today, New York City. If you have to go out, bundle up. If you run into any issues with your heat, report it to 311.

Testing is a critical weapon in fighting back #COVID19 , and at-home rapid tests are available at testing sites across the five boroughs. But how do they work? We'll walk you through it. ➡️

@NYPDONeill  Sewell and I are in lockstep on this: Public safety and justice are the prerequisites to prosperity. Our subways are the lifeblood of our city and we're going to keep them safe.

When Tom Richardson walked into Engine Company 227 in Brooklyn in 1980, he began a career that defined New York's Bravest. They still talk about his daring rescue in 1989 when he descended on a rope to save a boy in a burning brownstone. Congratulations on your retirement, Chief.

No one affected by the Bronx Fire is being asked to leave their emergency hotels. Period.   Families who can access their homes have the option to return if they want to, and hotel rooms are still available if survivors want one.

Working people like the team at @SteinwayAndSons  keep our city moving. We’re here for them. Join us in Astoria.

We are closely monitoring the hostage situation in Colleyville, Texas and we’re praying for a peaceful and safe conclusion. Out of an abundance of caution, the NYPD has deployed additional resources to key Jewish locations around the city tonight.

Dr. King's dream seemed complex and out of reach, but it wasn't. We have the power to deliver on his dream. For too long, our city hasn't taken action. That's going to change. #MLKDay 

When Charles McGee was asked what he was most proud of, he said: “my work as a Tuskegee Airman that helped bring down racial barriers and defeat the Nazis.” Rest in power General, and thank you. We've got the watch from here.
