CHICAGO (AP) – Backers of Illinois’ ban on concealed weapons vowed Wednesday to fight for continued controls on gun possession, a day after a federal appeals court struck down the nation’s last such prohibition as unconstitutional and ordered the state to craft a law allowing it.

Chicago aldermen joined gun control advocates in urging state Attorney General Lisa Madigan to appeal the ruling from the 7th U.S. Circuit Court of Appeals. Gov. Pat Quinn and Chicago Mayor Rahm Emanuel said they would work with legislators to come up with a new law that would be sure to protect the public.

“I think it’s important that we stress that public safety comes first,” said Quinn, an ardent supporter of gun control, adding that people with a history of mental illness who are involved in domestic violence should not be able to carry weapons.
