The Haley campaign did not immediately respond to a request for comment on Saturday. When reached by Reuters, the campaign declined to address the report.
Ms. Haley, who served as ambassador to the United Nations in former President Donald J. Trump’s administration, is the last serious candidate battling him for the 2024 Republican presidential nomination. She lost to Mr. Trump in the New Hampshire primary on Tuesday by 11 percentage points, and they have increasingly clashed over her decision to stay in the race.
A copy of the public safety director’s email was not immediately made available by officials in Kiawah Island, an affluent gated enclave south of Charleston, S.C., known for its beaches and golf courses. In 2019, The Post and Courier reported that Ms. Haley had bought a $2.4 million home on the island.
Mr. Harris, the public safety director, did not respond to a request for information on Saturday.
The day before Ms. Haley was targeted, a man called 911 to say that he had broken into the home of Shenna Bellows, Maine’s secretary of state and a Democrat. As the state’s top election official, she had just disqualified Mr. Trump from Maine’s primary ballot because of his actions during the Jan. 6, 2021, riot at the U.S. Capitol.
No one was at her home when officers arrived, according to Maine State Police.
Less than a week later, state capitols in Connecticut, Georgia, Hawaii, Kentucky, Michigan, Minnesota, Mississippi and Montana were evacuated or placed on lockdown after receiving bomb threats that the authorities later described as false and nonspecific.
