DERRYN Hinch faces a High Court fight to save his political career after the self-styled "human headline" admitted links to the United States that could disqualify him from the Senate.
Senator Hinch on Wednesday night acknowledged he had become the latest member of federal parliament caught up in the citizenship scandal that has rocked Canberra.
The Victorian senator has renounced New Zealand citizenship.
But he still holds a social security card from when he lived in New York - which makes him eligible to receive benefits from the US.
"I plan to raise the issue with the Solicitor-General and, if necessary, will refer myself to the High Court acting as the Court of Disputed Returns," he told the Herald Sun.
