The Secret Service is investigating a weird disturbance at a President Obama campaign stop over the weekend. Reporters at the Virginia Commonwealth University rally saw a woman wearing a burka adorned with US military pins and carrying what appeared to be a Koran hauled out of the rally by police after heckling from the audience, WTVR reports. Police say the woman was escorted out of the building after causing a disturbance, but was not arrested. She's heard protesting loudly as she's led out on a video taken at the scene.
