California Democrat Dianne Feinstein says Hillary Clinton has to come clean on the email scandal for her own good.
Senator Feinstein, appearing on NBC's Meet the Press, said Clinton needs to "step up and come out and state exactly what the situation is."
Clinton has been dogged over her use of personal email to conduct government business while she was secretary of state since the New York Times exposed the story last week. While Clinton is not the only cabinet level official to use a private email for official business, her use of a private email account, housed on her own server, has been described as exclusive.
At first, Clinton's camp denied any wrongdoing and claimed Hillary's emails would have been retained by the State Department because she emailed staff on their official accounts. It was later revealed that her closest staff also used secret, private email.
Democrats now worry this, as part of a larger narrative of the Clinton's playing by their own rules, could hurt her chances in 2016.
"She is the leading candidate, whether it be Republican or Democrat, for the next president...from this point on, the silence is going to hurt her," Feinstein said.
