Donald Trump's new campaign chief is registered to vote in the battleground state of Florida, using the address of a vacant house he does not live in.

According to a report by the Guardian, Stephen Bannon's active voter registration in Miami-Dade County, Fla., is in violation of election laws.

The house is vacant and is set to be demolished. Bannon, the recently appointed chief executive of Trump's presidential campaign, had rented the house for his ex-wife but did not live there. She moved out earlier this year and the two divorced seven years ago.

According to neighbors, the house has been abandoned for three months and Bannon has never appeared at the house.

Records held by the office of the county property appraiser show Bannon owns no property in his name in Miami-Dade.

Bannon, who is also the executive chairman of Breitbart News, has claimed that voter fraud is rampant among Democrats. He and the Trump campaign have claimed the election will be "rigged" in favor of Democratic nominee Hillary Clinton.

Under Florida law, voters must be legal residents of the state and of the county where they register to vote. Legal residency in Florida is defined as the place "where a person mentally intends to make his or her permanent residence."

"You must reside in Miami-Dade County," the election website for Miami-Dade states. "When you register to vote, an actual residence address is required by law."

A county spokeswoman did not respond to questions on Bannon. The Trump campaign also declined to comment.

Submitting false information regarding Florida voter registration is a third-degree felony punishable by up to five years in prison.
