A Barack Obama campaign phone bank at the UFT’s Lower Manhattan building was the scene of an anthrax scare today, we learned on a visit to the building tonight.

The phone bank received hate mail reading “Kill Barack” that was filled with a brownish-white powder today. Police spent more than six hours decontaminating the building along with four employees who came in contact with the substance, our source at the building said. CBS reports a similar event at an Obama campaign office in Philadelphia this afternoon.

The Obama campaign’s New York headquarters are housed inside the UFT’s building at 52 Broadway, a fact that is clearly displayed on the campaign’s web site.
