Authorities in cities across the country are investigating vandalism against Democratic offices, apparently in response to health care reform.

Vandals smashed the front door and a window at Rep. Gabrielle Giffords’ office in Tucson, Ariz. early Monday, hours after the Arizona Democrat voted for the health care reform package. Over the weekend, a brick shattered glass doors at the Monroe County Democratic Committee headquarters in Rochester, N.Y. And last Friday, a brick broke a window at Rep. Louise Slaughter’s district office in Niagara Falls, N.Y. Slaughter, a Democrat, was a vocal supporter of the health care reform bill passed by the House on Sunday.
