The FBI has arrested former Indiana state senator and congressional candidate Brent Waltz.

Federal agents arrested Waltz after conducting a search of his home in Greenwood on a warrant. That's all federal investigators would confirm, but court records in a Virginia federal court case show a political consultant in Maryland plead guilty to funneling thousands of dollars from a casino operator in Indiana to the campaign of congressional candidate from Indiana in 2015.

Waltz ran for Congress in 2015 and lost out to Trey Hollingsworth.

The FBI has not said if the court case in Virginia is connected to Waltz's arrest.
