Republican Senate Majority Leader John Flanagan nudged New York City Mayor Bill de Blasio to provide more information on how the city spends $9 billion in state funding for education as a precursor to considering an extension of mayoral control of public schools.

Flanagan is specifically taking issue with city Department of Education officials submitting a report on school finances that doesn’t adhere to state law.

“A fundamental shortcoming of this administration has been a lack of transparency and response to requests for information,” Flanagan wrote in the letter. “The lack of detail on how New York City spends the almost $9 billion provided to it by the State has been one of the key determining factors in a short term extension of mayoral control.”

The letter comes as Assembly Democrats are poised to back an extension of mayoral control for the next two years. Senate Republicans have indicated they will only support a 12-month extension of the policy, which expires in June.

Republicans in the Senate and de Blasio have had a strained relationship since he took office in 2013, pronouncing his support for a Democratic-led Senate.
