A man who impersonated a Secret Service agent could be in some hot water.
Investigators say he removed 3 people from a town hall meeting with the President last month.
An attorney for the three people says his clients were escorted out by the impersonator because they arrived in a car bearing a "No More Blood for Oil" bumper sticker.
The Secret Service has asked to talk with the three but was denied the request.
A criminal investigation continues.
