Ruth Bader Ginsburg, the US Supreme Court's eldest justice and de facto leader of its liberal wing, has been released from hospital after being admitted last week with a possible infection.
The 86-year-old has had a series of health scares this year, sparking speculation she may retire -- a move that would allow conservative US President
Donald Trump to nominate a replacement.
A feminist icon, Ginsburg is one of four liberals on the nine-justice court and has given no sign she is thinking of stepping down.
