Top law enforcement officials have countered a claim by Democratic Sen. Bill Nelson that Russian operatives had penetrated some county election systems in his home state of Florida. 

In a Monday letter obtained by Fox News, Homeland Security Secretary Kirstjen Nielsen and FBI Director Christopher Wray told Florida officials that while Russian spies “have previously demonstrated both the intent and capability to conduct malicious cyber operations,” there is no current evidence to suggest any meddling in the upcoming midterm elections in November.

“DHS and the FBI will continue to notify any victim of a successful cyber intrusion into their election network in any jurisdiction nationwide,” the letter, which was first reported by the Orlando Sentinel, stated.
