After Shooting at Trump Rally, Officials Say R.N.C. Security Is ‘Ready To Go’

Milwaukee was always an unlikely host for the Republican National Convention: small in population with 560,000 residents, short on hotel rooms and unaccustomed to holding large-scale gatherings.

The city is now facing even more scrutiny in the wake of an assassination attempt Saturday night against former President Donald J. Trump at a Pennsylvania rally. On Sunday, Milwaukee officials and the U.S. Secret Service spent the eve of the convention scrambling to reassure the public that the event would be safe, as delegates began arriving and thousands of protesters prepared to gather on Monday in a large demonstration near the convention site.

Even as workers this weekend were erecting fences, posting shiny signs and adding final touches as the first of 50,000 people descended on the city, party and local officials met to re-evaluate security plans.

At a news conference in Milwaukee, Audrey Gibson-Cicchino, the R.N.C. coordinator for the Secret Service, said that the agency was “ready to go” for the convention on Monday.

“We’re not anticipating any changes to our operational security plans for this event,” she said.

Omar Flores, a leader of the Coalition to March on the R.N.C., said at a news conference on Sunday that the attempted assassination of Mr. Trump should not affect the group’s plan to hold a rally and march on Monday aimed at conveying their views to the Republican delegates. It was expected to draw as many as 5,000 left-leaning protesters.

There is some uncertainty about how close to the Republicans’ meeting protesters will be allowed to march, as a dispute over that question has simmered for weeks. Mr. Flores said that his group intended to come “within sight and sound” of the Fiserv Forum, the main convention hall. “We have not had safety issues at any of our several marches or events, and we look forward to our family-friendly march tomorrow,” Mr. Flores said.
