"I don't care what the legal precedent is, I feel strongly that leadership needs to stand up and defend these police officers," said Steve Loomis, the head of the police union who is making the request.
Mr Loomis urged Governor John Kasich to declare a state of emergency and issue the temporary ban as protesters gathered in Cleveland a day before the four-day convention was due to begin.

Tensions have also been high between police and protesters amid a recent string of violence, which included the police shootings of two black men as well as an attack in Dallas that left five police officers dead.
On Sunday, the violence continued in Baton Rouge, Louisiana, where a gunman shot and killed three officers and injured three others, one critically, near the city's police headquarters.
