Illinois U.S. Senator Mark Kirk says North Korea faces instability after the death of dictator Kim Jong Il.
Kirk, a Republican, says regardless, the U.S. should attend the funeral of Kim Jong Il if invited by North Korea.
"We should sent a delegation because we should always try to build a new relationship with the regime even though it looks pretty bleak at this point," Kirk said.
