TALLAHASSEE, Fla. — A Florida jail inmate told the authorities that there was a plot to bomb Gov. Jeb Bush on Friday, but law enforcement officials said none of the inmate's information had been substantiated.
The inmate told of the plot in a letter to Bush late last month, officials said.
The State Department of Law Enforcement, the Secret Service and the Federal Bureau of Investigation investigated but found no proof of the threat, Tim Moore, the state law enforcement commissioner, said on Friday in a news conference here.
Moore refused to give specifics on the investigation, which was first reported by The Miami Herald on Friday.
During the investigation, two people were taken into custody on immigration violations, Moore said.
The Herald reported that the inmate told the authorities that at least four men with Arab names were trying to get someone to drive a truckload of explosives to Tallahassee to kill Bush.
The newspaper said investigators had been skeptical about the threat — the man had failed five polygraph tests — but on Thursday bomb-sniffing dogs detected the presence of something suspicious in a van that the inmate had told them about. No explosives were found in the van, The Herald reported.
Bush, who said he first learned of the threat last week, went about his workday as usual, even joking about the appearance of extra television cameras at a previously scheduled news conference where he announced an administration appointment.
"These things don't happen regularly to governors, but sometimes they do," Bush said. "There's nothing out of ordinary in this regard. We have no evidence to suggest that anything is going to happen here."
Bush said he not changed his daily routine, nor did he plan to limit public access to the governor's mansion, which periodically allows visitors. He noted an increased number of law enforcement officers guarding him on Friday, but he said he remained at ease.
"I have total confidence in their abilities and do not feel threatened," Bush said.
Bush said, however, that he warned his wife, Columba, and their three children on Thursday night that news about the threat would soon become public. He said he recalled that he had learned on television that his father, former President George Bush, had a heart murmur.
