TALLAHASSEE, Fla. (AP) - Florida law-enforcement authorities are closing several voter fraud investigations, although there are major cases from the 2012 election still pending.
 
The Florida Department of Law Enforcement has found no wrongdoing with the registration of 20 people who signed up through the Rock the Vote website. FDLE agents interviewed the people and said the information they gave was accurate.
 
Additionally, FDLE has closed one case against a person accused of voting in the states of Florida and Rhode Island due to a lack of evidence that the person existed. The case was initiated by a group called True the Vote.
 
FDLE is still investigating alleged fraud involving a company hired by the state's Republican Party to register voters. Authorities are also looking into fake letters that questioned the citizenship of voters.
