New York Gov. Andrew Cuomo and NY Sen. Charles Schumer say they'll join Connecticut Gov. Dannel P. Malloy in banning gun sales to those on federal no-fly lists.
Malloy proposed the ban on Thursday to use an executive order to ban the sales.
Leaders in New York will gather Monday on the third anniversary of the Sandy Hook massacre to close a loop hole that would facilitate the ban.
Malloy said that his order would make Connecticut the first state to do so and that state officials are working with the federal government to get access to the lists.
"If you cannot fly due to being on a government watch list, you should not be able to purchase a firearm while on that watch list as well," Malloy told reporters at the Capitol. "This is basic common sense. The American people get it."
The legislature and Malloy previously enacted gun limits that expanded the state's assault weapons ban and barred the possession and sale of large-capacity ammunition magazines following the Dec. 14, 2012, shooting deaths of 20 children and six educators at the Sandy Hook Elementary School.
State Police now perform background checks on those seeking permits to purchase guns in Connecticut. Pending federal approval, Malloy's order will require State Police to cross-reference the names of those seeking firearm permits with government watch lists.
Permits would be revoked for those who already have them but are found on watch lists.
Malloy said those denied a gun permit may be appeal to a firearm review board.
President Barack Obama has called on Congress to approve legislation to keep people on the no-fly list from buying guns. Gun rights advocates oppose the proposal because they say it violates the rights of people who have not been convicted of a crime.
Malloy said he is responding to the terrorist attacks in Paris that killed 130 people and in San Bernardino, California, that left 14 people dead. He said the Republican-led Congress has failed to act.
State officials will determine the "appropriate lists" to be included, whether they are no-fly lists or "some kind of combination of those who should not have weapons," Malloy said.
