Westchester County Executive Rob Astorino mocked the memorandum of understanding reached between Senate Republicans and Gov. Andrew Cuomo in a radio interview, calling the deal “useless.”

The MOU announced late Friday by Sen. James Seward essentially blocks funding for the creation of an ammunition purchasing database that State Police had struggled to develop this year.

While GOP lawmakers in the Senate are hailing the move as a victory for the Second Amendment, Astorino and other gun-rights proponents have said the agreement does little to change the gun-control measure approved in 2013.

“What’s the right word for BS? I think it’s a useless thing,” Astorino told Susan Arbetter on WCNY’s The Capitol Pressroom. “The issue is the SAFE Act itself — the SAFE Act should go.”

The agreement came after Senate Majority Leader John Flanagan, who replaced Dean Skelos as the top GOP conference member in May, pledged to enact changes to the gun control law after some upstate Republicans were disappointed that yet another Long Islander would lead the last vestige of Republican power in the state.

In the interview, Astorino pointed to the recent escape of two convicted killers from Clinton Correctional Facility and the desire of North Country residents to defend themselves.

“They were doing everything possible to stay alive, including kill more people,” Astorino said of the convicts Richard Matt and David Sweat. Matt was killed and Sweat was apprehended after three weeks.

“We’ve got rural homeowners who were basically told to stay in there home … and they were basically told to not have more than seven bullets in their guns.

Astorino has not seen eye-to-eye to Senate Republicans during his 2014 bid for governor.

He said empowering Democrats in the chamber “would be demonstrably worse” and urged Flanagan to steer the Senate GOP to a more assertive position in Albany.

“He’s the new leader, he gets an incomplete right now because he was just thrown into the process,” Astorino said. “The Senate Republicans have to stand for something. They have to go on offense. You don’t score points playing defense.”
