"They didn’t mean any of it," she said.

"If they were sincere about it, I think you’d have Republican members of Congress calling for an investigation. I haven’t heard that yet."

Clinton admitted her use of a private email server was a "dumb mistake," but, she added, "a dumber scandal."

Her comments come after The New York Times reported Monday that at least six members of Trump's White House have used private email addresses while conducting government business.

Current and former officials told the newspaper that former White House chief of staff Reince Priebus, former chief strategist Stephen Bannon and current advisers Gary Cohn and Stephen Miller sent or received government-related emails on personal email accounts, in addition to two staffers who were previously reported.

During the 2016 presidential campaign, Trump repeatedly targeted Clinton for her use of a private server while serving as secretary of State.

White House press secretary Sarah Huckabee Sanders said Monday all White House personnel "have been instructed to use official email to conduct all government-related work."
