Senate Majority Leader John Flanagan predicted a lengthy session on Wednesday, but would not say definitively whether he expects the Legislature to stay in Albany beyond the final scheduled day of the session.

“If that takes us beyond tonight — frankly, it’s the middle of the day, I don’t know,” he said.

Flanagan spoke with reporters after meeting with Gov. Andrew Cuomo in his office for about an hour. Speaker Carl Heastie was not in the meeting.

The Senate has at least 50 gubernatorial nominations to confirm, while legislative leaders and Cuomo continue to sort out an elusive agreement for extending rent control regulations, which expired this week.

“We’re obviously going to be in a very long day of session,” Flanagan said.

Meanwhile, Republican lawmakers have not budged on pushing for changes to rent control that are opposed by Democrats in the Assembly such as verification of income and residency.

“Our position hasn’t changed where we were a couple of days ago and earlier in the session,” Flanagan said. “The property tax cap we believe should be permanent. We put out a rent control bill we believe is in the best interests of the taxpayers and the people of the city of New York.”

Flanagan also dismissed a bill that was introduced by Assembly Housing Committee Chairman Keith Wright, which would extend rent control through the first month of 2016.

The Senate GOP bill, approved on Monday, would extend rent control for eight years.

“People talk about the value of rent control, we put out the longest extender of anybody. If you want to talk about maintaining the integrity of the program, I think an eight-year extender sends a message that would be a very good thing for the people who are in these apartments,” Flanagan said.

Senate Republicans continue to back a permanent tax cap, which is due to expire next year but is linked to rent control laws in the city and surrounding areas.

Flanagan said his conference supports “minor” changes to the cap, such as allowing for growth in payment-in-lieu of taxes.

“I can’t represent to you fairly that’s part of any final agreement because there isn’t one yet,” he said.
