Bob Etheridge is facing questions Monday after a video was posted online showing the North Carolina Democrat getting into a physical confrontation with two young men who eventually identified themselves as students and asked the congressman whether he "fully supports the Obama agenda."
"Who are you?" a clearly frustrated Etheridge replies when the two men approached Etheridge with a camera on a Washington street. When the purported students did not answer, Etheridge is seen slapping the camera out of one of the individual's hands.
Later in the video, which has clearly been edited, Etheridge is seen grabbing the wrist of one of the men and again repeatedly asking, "Who are you?...Tell me who you are."
"We are just here for a project," one replied. "We are just students, that's all we are."
In the video, currently posted on the website of Andrew Brietbart - a conservative commentator and online news aggregator - the students faces are obscured and they never fully identify themselves or their affiliation.
"I have a right to know who you are," Etheridge responded, still firmly gripping the man's wrist. The Democrat then briefly grabbed the individual's neck before letting him go.
Etheridge has represented North Carolina's second congressional district - located in the central part of the state – since 1997. He was reelected in 2007 with 67 percent of the vote.
