Hillary Clinton has attacked senior Trump administration officials for their use of private email servers – the very charge that upturned her own presidential campaign last year.

Donald Trump's son-in-law and senior advisor, Jared Kushner, admitted over the weekend that he had used private emails when the administration first took office in January.

It was subsequently disclosed that his wife Ivanka had also used a private account from the White House in February, before she became an unpaid federal employee in March.

Four other senior Trump officials – aides Gary Cohn and Stephen Miller, former advisor Steve Bannon and ex-chief of staff Reince Priebus – also used private accounts for official business.

“We’re finding with the latest revelations – they didn’t mean any of it. It’s just the height of hypocrisy,” Ms Clinton told Sirius XM radio this week.

“It is something that if they were sincere about I think you’d have Republican members of Congress calling for an investigation. I haven’t heard that yet.”

Hillary Clinton’s use of a private email server during her term as US Secretary of State was a central plank of Donald Trump’s election campaign, with crowds at Trump’s rallies often chanting “lock her up” when he raised the subject.
