Ohio Gov. John Kasich says he doesn't have authority to suspend the state's law allowing people to openly carry guns.

Kasich responded Sunday to a request by the Cleveland police union president for the suspension of the law during the Republican National Convention, which begins Monday.

The request by union president Steve Loomis followed Sunday morning's fatal shooting of three police officers in Baton Rouge, Louisiana.

Kasich says Ohio governors don't have the power to arbitrarily suspend federal and state constitutional rights or laws.

Kasich, a Republican, called law enforcement a noble and essential calling and said people are grieving again after new attacks on officers.
