Count Bernie Sanders in Ruth Bader Ginsburg’s corner in the Supreme Court justice’s escalating war of words with Donald Trump.

While remarking Wednesday on ABC’s “Good Morning America” that he would let Ginsburg herself speak to whether her recent criticism was inappropriate, Sanders added, “Let me very clear: I agree with what Justice Ginsburg said.”

Ginsburg’s comments in recent interviews with CNN, The Associated Press and The New York Times that the presumptive GOP nominee is a “faker” because he has not released his tax returns, joking that perhaps she might relocate to New Zealand and suggesting support for Hillary Clinton, drew fierce reaction from Trump, who questioned her mental faculties and called for her resignation earlier Wednesday. Trump earlier called upon Ginsburg to apologize to her Supreme Court colleagues.
