There was little evidence of major voting fraud on Tuesday, but a Texas county near Houston reported arresting a man for attempted fraud, adding to a handful of fraud-related arrests around the country in recent weeks.
According to the sheriff's office in Fort Bend County, the man claimed to be testing the system.
"What's interesting is that he said he was working for Trump," said Fort Bend County Sheriff Troy Nehls.
Nehls named the man as Phillip Cook Jr., 62, of Richmond, Texas, and said he was unable to confirm if he really worked for Republican Donald Trump or his campaign. Nehls said he did not have information on where Cook first voted but said the second attempt was at a local Baptist church.
"This is the first time I've seen this as sheriff. You hear of things like this taking place around the country but I had never seen it," Nehls said. "I said that we better place him under arrest and book him into the jail because you start comprising the integrity of the election by attempting to vote twice and we are not going to have that."
The sheriff did not say for whom Cook had voted.
While voting fraud is rare _ one study found just 31 credible claims of fraud amid more than a 1 billion ballots cast since 2000 _ there were several allegations of fraud on Tuesday and there have been a handful of arrests during the election.
In the weeks before Election Day, local police had filed voting fraud charges against individuals in Florida, Virginia and Iowa.
In Florida, officials arrested a 74-year-old old woman on Oct. 28 on charges of tampering with absentee ballots at the Miami-Dade Elections Department while working as a absentee ballot opener. In an unrelated case on the same day, a 33-year-old man was also arrested in Florida and charged with submitting false voter registration information while working on a medical marijuana legalization effort.
Also on Oct. 28, a 30-year-old Virginia man was arrested on charges of submitting falsified voter forms while working on a registration project.
In Des Moines, Iowa, a 55-year-old woman was arrested on Oct. 27 on charges of voting at two polling sites.
