1. NYPD detective asks Supreme Court to block vaccine mandate

A New York City police detective has asked the U.S. Supreme Court to stop the city from firing him and other workers for refusing to get vaccinated against COVID-19.

Lawyers for Detective Anthony Marciano asked the court Thursday for an emergency injunction that would block the city from enforcing a rule requiring all municipal employees to get vaccinated.

2. De Blasio discourages Niou from third party challenge to Goldman

Former Mayor Bill de Blasio said it wouldn’t be a good idea for Assemblymember Yuh-Line Niou to run against Democratic primary winner Dan Goldman on the Working Families Party line in November.

“I’m someone who very much appreciates the history of the Working Families Party and I think they’ve done a lot of good in this state,” the former Met told Errol Louis on “Inside City Hall” Thursday, saying he believes voters will go for the Democratic candidate during the midterm elections.

“I don’t find that particularly productive,” he said of the idea being pushed by Niou’s allies, including 2018 gubernatorial candidate and actor Cynthia Nixon.

3. MTA hosts contentious congestion pricing hearing

New Yorkers aired their concerns and also expressed support for congestion pricing at the first of six virtual public hearings on the MTA’s plan for the Manhattan toll. “I believe if the MTA were given a trillion dollars, they would find a way to spend it and then they would say they need more,” said one participant.

The proposed fee on drivers entering Manhattan’s busiest streets at the busiest times of day has drawn criticism from residents who live in the congestion zone south of 60th Street. There will be a tax credit for residents who make less than $60,000 year, but some say that’s not enough.

And Bhairavi Desai, the executive director of the New York Taxi Workers Alliance, called for congestion price exemption for taxi cab drivers on "Inside City Hall" Thursday.
