Supreme Court Justice Ruth Bader Ginsburg has been saying unflattering things about Donald Trump over the course of the past week in three different interviews. This week, Trump shot back, saying she should resign.

In less than a week, Ginsburg, 83, who was appointed to the Supreme Court in 1993 by President Bill Clinton, has given three interviews assailing the presumptive GOP nominee.

Trump responded by telling a New York Times reporter that Ginsburg's comments were "highly inappropriate" and she should leave her lifetime appointment sooner rather than later. "I went after Justice [Sandra Day] O'Connor in 2000 when at a dinner party on the night of the election, she said that the election of [Democrat Al] Gore would be a disaster". He just says whatever pops into his head and why hasn't the press been proper about his tax returns? She called out his ego and complained the press had been soft in its coverage.

Justice Ginsburg also asked a question about Trump during a thoughtful conversation with a respected legal analyst: "How has [Trump] gotten away with not turning over his tax returns?".

She launched her criticisms last week, with comments to the "New York Times", in which she spoke of barely being able to think about the impact Mr Trump would have on the future make-up of the court were he to win the White House in November.

Ginsburg said a Trump presidency would be so bad that "I don't even want to contemplate that" and made a joke about moving to New Zealand. For the country it would be four years. Supreme Court justices are exempt, which makes no sense because they are the most powerful, influential, visible and well-known members of the entire federal judiciary.

Rep. Randy Weber, R-Texas, said in a statement Wednesday that Ginsburg's remarks " are the antithesis of Lady Justice and in direct violation for what the highest court in the land stands. Many others are calling Ginsburg's comments inappropriate.

"I think that Trump is a total opportunist", Sanders said.

Some Democrats said Ginsberg may have stepped too far as a judge on the country's top court. "That shows bias to me", Ryan said during a CNN town hall.

Ginsburg was not immediately available for comment on Trump's remarks and the editorial. If Trump is elected then the Supreme Court will invariably hear cases brought against his administration. In an editorial on Wednesday, the New York Times urged Ginsburg to uphold the court's tradition of silence in political campaigns. While Supreme Court justices are not held to that standard, the Post thinks they probably should be.

"Even if it were unenforceable, a code would at least formalize public expectations for the justices' conduct", legal scholar Steven Lubet wrote on the website Legal Ethics Forum. Donald Trump is a faker.

Are justices like Ginsburg allowed to publicly take a side in a presidential election or any other election for that matter?
