Police are investigating after a Republican headquarters in Volusia County, Florida, was riddled with bullets this past weekend, party leaders said. At least four shots were fired overnight Sunday, Volusia County Republican Chairman Tony Ledbetter confirmed to Fox News on Monday. Ledbetter said "everything was OK" when volunteers left the building at about 4 p.m. Sunday, but when they returned at 9:30 a.m. Monday, at least one window was broken.
