TALLAHASSEE, Fla. (AP) — What first appeared to be an isolated problem in one Florida county has spread statewide, with election officials in at least seven counties telling prosecutors or state election officials about questionable voter registration forms filled out on behalf of the Florida Republican Party.

State Republican officials fired Strategic Allied Consulting, the company they had hired to register voters, and on Thursday filed an election fraud complaint against it with state officials.

“We are doing what we can to find out how broad the scope is,” said Brian Burgess, a spokesman for the state party.

The company said that it was cooperating with elections officials and that the suspect forms had been turned in by one person, who was fired. “Strategic has a zero-tolerance policy for breaking the law,” Fred Petti, a company lawyer, said Thursday.
