Ms. Triolo, 52, a moderate Republican in her fourth term as mayor, suggested that Mr. Hardy’s rant was intentional grandstanding for attention — he is running for a seat in the State House. She said that his actions amounted to bullying and that the issue of utility shut-offs had been inaccurately portrayed.

“He hijacked this meeting to talk about something that was not even on the budget,” she said. “He was aggressive and completely out of order. That snippet was taken out of context. It was damaging and gave our city a black eye.”

Mr. Bornstein acknowledged that service to dozens of residents had been suspended earlier, but he said no utility disconnections had taken place since a moratorium was announced on Wednesday, the day before the explosive meeting. Those customers had already had their service restored, he said, and fines had been reversed.

The city later announced additional protections for city workers, including paid leave, and closed the public golf course, but it left the beach — which attracts about 3,000 visitors daily — open until the governor, Ron DeSantis, ordered beaches closed in Broward and Palm Beach Counties.
