PITTSBURGH (CBS Pittsburgh) — An office that supports groups that are against President Obama was vandalized for the second time in less than two weeks.

According to the Pittsburgh Post-Gazette, vandals spray-painted messages on the anti-Obama office – which is supported by American Majority Action — located in Squirrel Hill.

Pittsburgh police tell the Post-Gazette that surveillance video catches two people spray-painting graffiti on the building Nov. 1. The first incident occurred Oct. 20.

The “Support Israel? Fire Obama” banner was changed to “Hire Obama.” The vandals also spray-painted “Elect Obama” and Jewish stars on the office windows.

Josh Wander, the office’s coordinator, told the Post-Gazette that dozens of “Support Israel” yard signs have been stolen from people’s property.

The city’s Graffiti Task Force is conducting the investigation. No suspects have been named in the case.
