ORLANDO, Fla. — A swing through Florida proved no sunny retreat for Gov. Chris Christie on Saturday, as well-organized protesters hounded him outside a Republican fund-raiser here, a powerful ally in the New Jersey State House rebuked the governor’s office and new allegations emerged that his administration tried to intimidate a New Jersey elected official.

Mr. Christie’s trip, which was supposed to showcase his political resilience after the rockiest period of his governorship, was overshadowed by claims from the mayor of Hoboken, N.J., Dawn Zimmer, a Democrat.

In a television interview on Saturday, she said that two high-ranking aides to Mr. Christie had threatened to withhold money for Hurricane Sandy recovery to her hard-hit city if she did not support a real estate development that the governor wanted built in her jurisdiction.

Speaking on MSNBC, she produced journal entries that she said documented conversations in which Lt. Gov. Kim Guadagno and Richard E. Constable, the commissioner of the Department of Community Affairs, told her that if she wanted the money, she had to approve the project. The financial assistance, Ms. Zimmer said, was held “hostage.”
