There may be jitters in Cleveland after several people were injured during a rally for Donald Trump last night in New Mexico.

Protestors threw burning t-shirts, plastic bottles and other items at police officers. They also toppled trash cans and barricades outside the Albuquerque Convention Center.

Police returned with pepper spray and smoke grenades.

On Wednesday the mayor’s office in Cleveland outlined plans for how protestors will be handled at this summer’s Republican National Convention when Trump comes to town.

For the first time, the Secret Service’s RNC point person was present.

Special Agent Ron Rowe has been working with about two dozen subcommittees to prepare and helped reveal the official “event zone” where activities will be held this summer.

It includes the official parade route, bordered by West 20th to the West, the Innerbelt to the east, and Lorain Carnegie Bridge to the south.

A so-called “secure zone,” where the general public will not be able go, has not been released.

“We will do this in a coordinated rollout prior to the event, weeks before the event will commence,” Rowe said.

Officials also said demonstrators can reserve two city spaces: Willard Park next to City Hall and Perk Park across from Reserve Square.

They are also adding new rules, requiring all organizers to reapply for permits online starting Tuesday.

The American Civil Liberties Union had threatened to sue if permits were not approved by June 1st.

Richard Horvath, Cleveland’s Corporate Counsel, assured them Wednesday that the city "will move very quickly" once a completed application comes in.

In the meantime, concerns remain when it comes to police staffing.

“We’re not at full strength where we want to be,” Cleveland Police Chief Calvin Williams said. “But we’re very close to that. You know every day I sign agreements with outside agencies to come and help secure the convention. We’re getting there. We’re close.”

He knows there will still be pop-up protests, and it is not illegal to simply gather on a sidewalk. All of that, he said, will be handled case by case.
