A fire on Sunday blazed through the North Carolina mill where former Sen. John Edwards (D-N.C.) and his father once worked, reports WTVD in Raleigh.

Firefighters from 20 departments responded to the fire at the abandoned Milliken Mill in Robbins. No one was injured. Investigators have yet to announce the cause of the blaze.

Edwards announced his first presidential bid in 2003 from mill. In both of his presidential campaigns, he often talked about growing up as in modest surroundings as the son of a mill worker.

Two weeks ago, he admitted having an extramarital affair and ruled out speaking at the Democratic convention, despite still holding delegates that he won in the Iowa caucuses and early presidential primaries.
