Rep. Bob Etheridge, a Democrat, is seen in an amateur video grabbing the wrist and neck of an unidentified young man after he approached the congressman and asked if he supported the "Obama agenda."
Etheridge is then seen trying to snatch a cell phone camera out of the student's hands. He then grabs the man's wrist and refuses to let go.
"Who are you!" the seventh-term congressman demands. "Tell me who you are ... I have a right to know who you are."
Another man, not seen on camera, then tells Etheridge, "We're just here for a project."
When the student asks Etheridge to "please let go of me," the congressman then grabs him by the neck.
